The Mighty Hercules, capable of flying about 18 hours without refueling, has been the mainstay of the US Air Force s Hurricane Hunters program since 1999.Galveston's most memorable hurricane is the Great Storm of 1900, which caused an estimated 6,000 to 12,000 fatalities and is still the deadliest natural disaster in US history.Such a rotation, in addition to maximum sustained winds of 39mph 35 knots , is required for the National Hurricane Center to name a storm.After flying through all four quadrants of the storm to ensure that there is indeed a closed circulation, the mission will then attempt to get a fix on the center of circulation.For our tour, however, the cargo compartment was largely empty except for Captain Luke Caulder, who stood by to answer any questions.The Gulfstream IV, managed by NOAA, visited Galveston's Scholes Field along with the Mighty Hercules.
If you read anything about Typhoon Nepartak, it probably will mention early on that it was the strongest storm to make landfall on Taiwan in 45 years.And yes, wind speeds topping 150 mph are very impressive.Of all the things that pose threats to people in the path of a tropical cyclone—rain, storm surge, flooding—wind is near the bottom.Yet it is central to every major cyclone classification system.It worries me that we focus on scale and category when what we know from hurricanes and trop cyclones in general we see most of deaths from water, says Marshall Shepherd, director of atmospheric sciences at the University of Georgia.He s referring to the various scales used to measure storm intensity.
Tropical storm Hermine forming in the Gulf of Mexico yesterday.Millions of Americans are preparing for a wet and wild Labor Day weekend as Tropical Storm Hermine bears down on the southeast, threatening to dump up to ten inches of rain over portions of northwest Florida and southern Georgia through Friday.The storm, which NOAA s National Hurricane Center upgraded from a tropical depression late yesterday, continues to intensify and could attain hurricane strength by the time it makes landfall later today.Hurricane and tropical storm warnings and watches are in effect for parts of northwest Florida, southwest Georgia, and eastern Alabama.GIF Image: National Hurricane CenterAfter making landfall, Hermine is on track to march up the coast in a northeasterly direction, possibly delivering tropical rains as far north as Boston by the weekend.
The National Hurricane Center s latest forecast notes describe—with bureaucratic glee, if such a thing exists—a confluence of conditions that might lead to Hermine ripening into a hurricane as it travels towards the north Atlantic.Hermine made landfall early Friday morning on the Gulf Coast of Florida, breaking that state s 11-year hurricane drought.Since then, it has moved north—weakening, as these storms do when they travel over land.By the time you read this, it will probably have returned to the sea via one of the Carolinas.But besides the weakening, this storm is not behaving as expected.Very tall storms tend to have clouds with colder tops.
GIF Hermine s eastward move Image: GIF made from NOAA satellite footage Post-tropical Cyclone Hermine took an unexpected veer east, which means that some of the worst of the rains and winds could happen out to sea if it continues on its trajectory.But even on that path, it could still send us a wave of storm surge floods.The National Hurricane Center s latest forecast shows Hermine continuing to move offshore and north through Monday—which is some good news, noted the National Hurricane Center s Director Rick Knabb in a briefing this morning.But, the move could also trigger Hermine to develop hurricane-force winds tonight and Monday due to the warmer waters it will travel over, which could push water to the shores even harder.NHC is warning that rising waters could bring life-threatening inundation over the next 36 hours.
Until Hermine blew through the Florida Panhandle and up into Georgia, Florida had experienced a pleasant, hurricane-free few years.In fact, as The Weather Channel noted, Florida went nearly eleven years without a single hurricane making landfall.The last hurricane to set foot in Florida was Hurricane Wilma, a Category 3 storm that made landfall in south Florida back on October 24, 2005.Since then 68 Atlantic-based hurricanes have skipped the Sunshine State—more than twice the previous record of hurricanes.That s alarming as, according to the National Hurricane Center, 40-percent of Atlantic and Gulf-based hurricanes from 1851-2010 affected Florida.The state has more coastline than any other state touching the Gulf of Mexico or the Atlantic, so the odds were never in Florida s favor.
Since yesterday evening, Hurricane Matthew has gathered strength and is on a collision course with the Caribbean.Here s what we know about the strongest hurricane to hit the region since 2007.Matthew hit Category 5 in the early hours of Saturday morning, becoming the first to do so since Hurricane Felix in 2007.It has dipped back down to a category 4 now and is still estimated by the National Hurricane Center in Miami to have winds of 155 mph.This morning, the hurricane briefly drenched Colombia as a it went through the northern tip of South America.Heavy flooding was reported and authorities say at least one person is dead as a result of the storm.
After a bout of rapid intensification last night, Hurricane Matthew has now achieved Category 3 status, packing 120 mph winds.It s first major Caribbean hurricane since Sandy, and the strongest to develop in this particular region since 2008.According to the US National Hurricane Center, the storm is expected to maintain its strength and possibly intensify further through the weekend as it rumbles toward Jamaica, reaching Hispaniola and eastern Cuba by early next week.Matthew currently sits a little over 400 miles southeast of Kingston and just 85 miles north of Colombia, where a tropical storm warning is in effect.A hurricane watch may be issued for Jamaica as early as later today.Where exactly the storm is headed next, and whether the US will see any impacts, is not yet clear.
The GOES East satellite captured this image of Hurricane Matthew approximately 220 miles southeast of Kingston on October 3rd.Hurricane Matthew made landfall in Haiti this morning, becoming the first Category 4 hurricane to hit the impoverished island nation dead-on in over fifty years.According to the National Hurricane Center, the life threatening storm made landfall around 7 am EDT on Tuesday, near Les Anglais in western Haiti.By that time, parts of the country had likely already experienced upwards of 20 inches of rain.More torrents today will increase the danger of flash floods, mudslides, and surges of 7 to 10 feet.Haiti, the poorest nation in the Western Hemisphere, is about the worst possible place a storm like this could have hit.
The most serious storm to hit the East Coast in over a decade is close to making landfall with southern Florida.From there, it s expected to move up the coast, hitting parts of Georgia, South Carolina and possibly North Carolina.Rick Scott warned that this storm will kill you earlier today — it s important to know where the storm is headed.DON T MISS: Under no circumstances should you buy a Galaxy Note 7The best resource for tracking Hurricane Matthew is the National Hurricane Center, which labels and tracks all storms that come near the US.The Hurricane Center publishes up-to-date forecasts for the storm, including maps of the predicted path, forecasts and written advisories for areas that are going to be hit.
Reuters - The coast-hugging path that forecasters expect Hurricane Matthew to take as it moves up the Atlantic seaboard on Friday and Saturday could make the storm one of the most devastating ever to hit the U.S. Southeast, according to experts.If Matthew skirts the coast of Florida, Georgia and South Carolina as experts expect, rather than slamming directly into land as most hurricanes do, the storm would keep drawing energy from the warm ocean waters, fuelling its destructive force."Once they make landfall, they will dissipate, but in the case of Matthew, it is going to be half over the ocean and continue to gain energy and hold together for much longer," said Isaac Hankes, a weather research analyst at Lanworth Inc, a company owned by Thomson Reuters Corp.After killing nearly 300 people in the Caribbean, the hurricane was likely to remain a Category 4 storm on the five-step Saffir-Simpson scale as it approaches the United States, according to the U.S. National Hurricane Center.As a consequence, the slow-moving storm, sporting winds of up to 140 miles per hour 225 km per hour , could prove to be more devastating than most hurricanes, even those that are just as powerful but slam directly into a single state."If it can live along the coast for a day and a half, it is going to be doing damage in terms of cost," said David Nolan, professor and chair of the Department of Atmospheric Sciences at the University of Miami.
Hurricane Nicole, about 270 miles southwest of Bermuda in this image captured by the GOES East satellite last night.Just as Hurricane Matthew was bearing down on the United States last week, tropical storm Nicole was getting organized to the east.After a bout of rapid intensification yesterday, the storm is now a major hurricane, and it s closing in on Bermuda, which could see a direct hit in just a few hours.Packing maximum sustained winds of 125 mph 205 kph , Nicole has been downgraded to a Category 3 storm in the latest National Hurricane Center advisory, after becoming the island nation s first Category 4 threat in nearly 80 years last night.Despite gradually weakening, Nicole is still extremely dangerous, with the expectation that this storm will remain a major hurricane Category 3 or higher as it passes Bermuda.The storm is currently located about 55 miles 85 km to the southwest.

Just one hurricane has ever formed in the northern Atlantic Ocean, Caribbean Sea, or the Gulf of Mexico in the month of March—a time when the oceans are still cold from the winter months in the northern hemisphere.This occurred in 1908 with an unnamed hurricane that, according to the Atlantic Hurricane database, reached sustained winds of 100mph and caused damage in the Caribbean islands.As the 1908 cyclone formed long before the National Hurricane Center existed, there has never been a "named" storm in March.That could change next week, as an area of low pressure may develop several hundred miles to the east of Florida, in the Atlantic Ocean.This storm system is unlikely to be a major threat to landmasses, with the possible exception of Bermuda.Due to the rarity of March cyclones, however, it would garner significant attention.
Early hurricane seasonal outlooks have been issued and are calling for an "average to slightly below" average Atlantic hurricane season.The National Hurricane Center issues a cone to indicate information on track forecasts.The size of each circle is set so that two-thirds of historical official forecast errors over a 5-year sample fall within the circle.Over the years, I have seen quite a few misinterpretations of the cone by the public, media, and stakeholders.That is the similar logic to saying meteorologists are wrong because it rained when there was only a 20% chance of rain.In his 2013 blog, University of Miami tropical meteorology expert Brian McNoldy wrote,
Although the Atlantic hurricane season begins June 1, the bulk of the tropical activity typically clusters during the middle months of August, September, and October when the seas reach their peak temperatures.This year has already been unusual, however, with the formation of highly rare tropical storm in April—Arlene, which meandered around the open Atlantic Ocean for a few days.Now, the tropics are becoming active again.For several days the National Hurricane Center has been calling attention to two systems, one near the southern Gulf of Mexico, and the other to the northeast of Venezuela in the Atlantic.Both systems have a 90 percent chance of becoming a tropical depression or storm, according to hurricane forecasters at the Miami-based center.For interests in the United States, the storm moving into the Gulf of Mexico today presents a legitimate threat.
Tropical Storm Greg appears to be less-rounded and more elongated on satellite imagery from NOAA's GOES-West satellite.Greg is still over 1,500 miles east of Hawaii.NOAA's GOES-West satellite captured an infrared image of Tropical Storm Greg on July 24 at 8 a.m. EDT (1200 UTC).The image revealed a less-rounded tropical cyclone.The National Hurricane Center noted the reason for the change in shape: "Greg's convective structure is gradually deteriorating, likely due to very dry air in the surrounding atmosphere."NOAA manages the GOES series of satellites, and NASA uses the satellite data to create images and animations.
NASA-NOAA's Suomi NPP satellite captured an image of Hurricane Hilary as it continued to strengthen.The National Hurricane Center expects Hilary to become a major hurricane on July 27.Hilary is one of three active tropical cyclones in the Eastern Pacific Ocean, and the closest storm to any land area.When the Suomi-NPP satellite passed overhead, it provided an image of the tropical cyclone train of storms.On July 24, 2017 at 6:12 p.m. EDT (2212 UTC) the Visible Infrared Imaging Radiometer Suite (VIIRS) instrument aboard NASA-NOAA's Suomi NPP satellite provided a visible-light image of Hurricane Hilary.The VIIRS image showed a compact hurricane with a tight band of powerful thunderstorms circling the low-level center of circulation.
Tropical Depression Greg appears as a ghostly swirl of low clouds on satellite imagery from NOAA's GOES-West satellite on July 27.NOAA's GOES-West satellite captured an infrared image of Greg on July 26 at 11 a.m. EDT (1500 UTC).The image showed that Greg's circulation consists of a tight swirl of low clouds with a few small patches of deep convection.Strong vertical wind shear is affecting Greg now, pushing the clouds away from the center of circulation.The National Hurricane Center (NHC) noted at 11 a.m. EDT (1500 UTC), the center of Tropical Depression Greg was located near 18.1 degrees north latitude and 141.0 degrees west longitude.It was about 965 miles (1,550 km) east of South Point, Hawaii.
Thunderstorm development on the eastern side of Tropical Storm Irwin appears to have improved in infrared imagery from NOAA's GOES-West satellite.NOAA's GOES-West satellite captured an infrared image of Irwin on July 28 at 9:30 a.m. EDT (1330 UTC).The image showed recent improvement in the thunderstorm banding feature wrapping around the eastern half of the cyclone.In the image, it appeared that the northern and eastern quadrant of the storm had a larger concentration of thunderstorms than rest of the storm.The National Hurricane Center (NHC) noted at 5 a.m. EDT (0900UTC) the center of Tropical Storm Irwin was located near 14.9 degrees north latitude and 124.8 degrees west longitude.It was about 1,120 miles (1,800 km) west-southwest of the southern tip of Baja California, Mexico.
