The first major tropical storm from the gulf this season is on its way, and all four major mobile carriers are knee-deep in preparations to ensure their networks stay as solid as possible.It's possible that it'll make landfall as a hurricane on Saturday, the National Hurricane Center told CNET sister site CBS News, with 10 to 20 inches of rainfall expected in Louisiana and southwest Mississippi.Kyle Malady, Verizon CTO, said "running to a crisis" to help communities by ensuring consumers, first responders, public safety teams and enterprises remain connected is fundamental to his carrier.Some of the work Verizon has done includes prepping surveillance drones; setting up storm command centers in network facilities able to withstand category 5 winds; inspecting backup generators, fiber rings and HVAC systems at its cell sites; organizing portable emergency equipment to be deployed quickly to restore any damaged connections; pre-arranging fuel deliveries so tankers are in place to quickly respond if power is lost; and adding a swathe of portable cell sites with secure, dedicated satellite links.Verizon is also working with first responders through the Verizon Response team to "mobilize charging stations, devices, special equipment, emergency vehicles and more to support local, state and federal agencies across the US."AT's Tropical Storm Barry preparations have involved topping off fuel generators, testing its high-capacity backup batteries located at cell sites, protecting physical network facilities from the potential of flooding, storing network recovery and emergency response equipment in strategic locations for fast deployment and of course ensuring FirstNet has dedicated deployable network assets for public safety agencies ready to go.
When it comes to hurricanes, it’s all in a name.Katrina will forever bring to mind the unbridled devastation in Louisiana in 2005 as one of the costliest hurricanes in the U.S. on record.Maria recalls the destruction and massive loss of lives – particularly in Puerto Rico and the U.S. Virgin Islands – in 2017.With Maria, nearly 3,000 people in Puerto Rico were killed.And Harvey, also one of the costliest storms, is reminiscent of the catastrophe it brought to Texas and Louisiana in 2017.For Atlantic hurricanes, the National Hurricane Center (NHC) recycles a list of names every six years – a process that is maintained by the World Meteorological Organization, the NHC explained.

New Orleans residents are preparing for Tropical Storm Barry, which could develop into a hurricane, to make landfall on Saturday.Visit Business Insider's homepage for more stories.Scientists can't definitely say whether Barry was directly caused by climate change, but they agree that warming overall makes storms and hurricanes more devastating than they would otherwise be.That's because higher water temperatures lead to sea-level rise, which causes flooding during high tides and in the event of storms surges.Climate scientist Michael Mann previously wrote on Facebook that Hurricane Harvey — which flooded Houston, killed more than 100 people, and caused $125 billion in damages — "was almost certainly more intense than it would have been in the absence of human-caused warming, which means stronger winds, more wind damage, and a larger storm surge."Hurricanes are vast, low-pressure tropical cyclones with wind speeds over 74 mph.

NASA's Aqua satellite passed over the Gulf of Mexico and took the temperature of Potential Tropical Cyclone 2 as it moved westward through the Gulf of Mexico.NASA found the very cold cloud tops indicating the storm had potential for dropping heavy rain.Infrared light enables NASA to take the temperatures of clouds and thunderstorms that make up tropical cyclones.The stronger the storms are indicate that they extend high into the troposphere and have cold cloud top temperatures.An infrared look by NASA's Aqua satellite on July 10, 2019 at 3:23 p.m. EDT (1923 UTC) revealed where the strongest storms were located within Potential Tropical Cyclone 2.The Atmospheric Infrared Sounder or AIRS instrument aboard NASA's Aqua satellite analyzed cloud top temperatures and found cloud top temperatures of strongest thunderstorms as cold as or colder than minus 63 degrees Fahrenheit (minus 53 degrees Celsius) circling the center (which is still not well-defined) and in thunderstorms northwest of the center, extending over southern Louisiana.

A massive complex of thunderstorms over the southeastern United States slid into the northeastern Gulf of Mexico and now has the potential to develop into a tropical cyclone.NOAA's National Hurricane Center or NHC in Miami, Florida issued the first advisory of Potential Tropical Cyclone Two and NOAA's GOES-East satellite and NASA's GPM satellite provided views of the storm.On July 10 at 11 a.m. EDT (1500 UTC), NOAA's GOES-East satellite provided a visible image of the developing storm.The Global Precipitation Measurement mission or GPM core satellite passed over the developing area of low pressure early on July 10 and found rain was falling at a rate of more than 50 mm (about 2 inches) per hour.GPM is a joint mission between NASA and the Japan Aerospace Exploration Agency, JAXA.NHC noted, "A tropical cyclone is expected to form by Thursday [July 11] over the north-central Gulf of Mexico.
Space may be the best place to watch a hurricane.You're far from the danger, but still have an incredible view of the action.On Tuesday, the National Oceanic and Atmospheric Administration's GOES West satellite delivered a stirring look at the heart of Hurricane Barbara, the first major Eastern Pacific storm of 2019.The satellite footage shows the eye of the hurricane, which is packing maximum sustained winds of almost 130 mph (209 km/h).It's now classified as a category 4 storm, one slot below a top-level category 5.NOAA's National Hurricane Center said Barbara could even strengthen a little more.

System 91L is an area of tropical low pressure located in the Bay of Campeche.On June 3, when NASA-NOAA's Suomi NPP satellite passed the western Gulf of Mexico, it captured an image of the storm that showed its extensive reach.The Visible Infrared Imaging Radiometer Suite (VIIRS) instrument aboard Suomi NPP provided a visible image of the storm.The VIIRS image showed fragmented bands of thunderstorms around System 91L's circulation center which filled the Bay of Campeche and stretched north into the western Gulf of Mexico.System 91L's clouds extend from Mexico's Yucatan state to the west bordering and including the states of Campeche, Tabasco, Veracruz and as far north as Tamaulipas.At 8 a.m. EDT on June 4, NOAA's National Hurricane Center or NHC noted that System 91L now has a 40 percent chance to form into a depression over the next two days.
NASA's Aqua satellite used infrared light to analyze the strength of storms in the developing low pressure area designated as System 91L is it moved through the Gulf of Campeche just north of Mexico's Yucatan Peninsula.Infrared data provides temperature information, and the strongest thunderstorms that reach high into the atmosphere have the coldest cloud top temperatures.On June 3 at 4:05 a.m. EDT (0805 UTC), the Moderate Imaging Spectroradiometer or MODIS instrument that flies aboard NASA's Aqua satellite gathered infrared data on developing System 91L.Strongest thunderstorms created a southern ring around the center from west to east, where cloud top temperatures were as cold as minus 80 degrees Fahrenheit (minus 62.2 Celsius).Cloud top temperatures that cold indicate strong storms with the potential to generate heavy rainfall.Those strongest storms were located just off the coast of the state of Campeche and the eastern part of the state of Tabasco.
Hurricane Michael smashed into Florida on Oct. 10 last year, with the state's governor, Rick Scott, calling it an "absolute monster."The storm was directly responsible for 16 deaths and left parts of the state's panhandle devastated.The hurricane was even worse than we knew at the time.The National Oceanic and Atmospheric Administration's National Hurricane Center finished analyzing the storm and announced Friday it has been upgraded to a category 5 from a category 4 at landfall.That one step up can make a difference in how we view the hurricane.The storm's estimated intensity at landfall is now pegged at 140 knots (160 mph, 257 km/h).
Categories 3, 4, and 5 are designated "major" hurricanes.Eventually, after much debate, hurricane scientists decided that the Saffir-Simpson scale should only reference wind speed (and no longer storm surge), and that the National Hurricane Center would de-emphasize its use in its forecast products and instead focus on the threats posed by any given storm—be it damaging winds, storm surge, or inland flooding from heavy rainfall.The Saffir-Simpson scale was retained, however, because most Americans were familiar with it, and it remained a useful tool to very generally identify the threat level of any given storm.Issuing warnings for hurricanes is a messy business, not least because the forecasts can and often do change, and because emergency managers desire a simple and clear message they can deliver to residents and business owners.Harvey: This is probably the worst US flood storm ever; I’ll never be the sameNow, the situation is likely to become more confusing.
Of course, there is no question the internet giants should be under greater regulatory scrutiny, though creating the red-tape maze does take time.The Digital Platforms Inquiry Preliminary Report released by the ACCC is just the first bureaucratic step in the dance which will take place over the coming months.Google and Facebook are in the crosshairs, though how long it will take to overhaul the dated and swiss-cheese like rules is anybody’s guess.“The ACCC considers that the strong market position of digital platforms like Google and Facebook justifies a greater level of regulatory oversight,” said ACCC Chair Rod Sims.But when their dominant position is at risk of creating competitive or consumer harm, governments should stay ahead of the game and act to protect consumers and businesses through regulation.”There are several issues which are being raised through the report, though the important one seems to be the breadth and depth of influence which the internet players can wield.
Visible from NASA's Aqua satellite revealed the extent of Tropical Storm Xavier into western Mexico from its position just off-shore from Mexico's Jalisco state.Tropical Depression Twenty-Five-E (25E) formed on Nov. 3 and strengthened in a tropical storm on by 11 p.m. EDT that day.Xavier has continued to hug the coast of western Mexico since it formed.On Nov. 4 a visible image from the Moderate Resolution Imaging Spectroradiometer or MODIS instrument aboard NASA's Aqua satellite showed an organized storm with a thick band of powerful thunderstorms circling the center.A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area.The National Hurricane Center noted at 11 a.m. EDT the center of Tropical Storm Xavier was located near latitude 18.5 degrees north and longitude 106.2 degrees west.
Hurricane Oscar has transitioned into an extra-tropical low pressure area in the northeastern Atlantic Ocean.The Global Precipitation Measurement mission or GPM core satellite provided a look at rainfall occurring within the storm.The National Hurricane Center defines "extra-tropical" as a transition that implies both poleward displacement (meaning it moves toward the north or south pole) of the cyclone and the conversion of the cyclone's primary energy source from the release of latent heat of condensation to baroclinic (the temperature contrast between warm and cold air masses) processes.It is important to note that cyclones can become extratropical and still retain winds of hurricane or tropical storm force.On October 31, 2018 at 8:43 a.m. EDT (1243 UTC) the GPM core observatory satellite had a pass over hurricane Oscar.The hurricane had maximum sustained winds of about 74.8 mph (65 knots) and was moving toward the northeast while becoming more extratropical in appearance.
Of course, tropical cyclones have one eye and with Halloween on the horizon, false-colored infrared imagery from NASA's Aqua satellite brought out that eye in this small tropical monster with a tail of thunderstorms.Cloud top temperatures determine strength of the thunderstorms that make up a tropical cyclone.The colder the cloud top, the stronger the uplift in the storm that helps thunderstorm development.Basically, infrared data helps determine where the most powerful storms are within a tropical cyclone.The Moderate Resolution Imaging Spectroradiometer or MODIS instrument aboard Aqua provided that infrared data on Oct. 30 at 1:40 a.m. EDT (0540 UTC) MODIS data showed cloud top temperatures in strongest storms around Oscar's eye were as cold as or colder than minus 70 degrees Fahrenheit (minus 56.6 degrees Celsius).The National Hurricane Center or NHC said " Cloud-top temperatures have warmed a bit overall, and the convective pattern is becoming more asymmetric as dry air is infiltrating the southern and eastern part of Oscar's circulation.
