As Hurricane Helene continues making its approach towards Florida — now at Class 2 standing — satellites in Earth orbit have been watching from above.
The GOES-16 spacecraft specifically, operated by NASA and the Nationwide Oceanic and Atmospheric Administration (NOAA), has delivered fairly a little bit of Helene footage, exhibiting the storm gaining energy whereas heading away from the Gulf of Mexico area and towards the southeastern U.S. “Dawn on intense convection inside an intensifying Hurricane Helene this morning,” the Cooperative Institute for Analysis within the Ambiance (CIRA) wrote in an X submit (previously Twitter) on Thursday morning (Sept. 26).
The storm, which NOAA calls probably “life-threatening” resulting from wind speeds and projected ranges of flooding, is anticipated to make landfall in Florida on Thursday night. By that time, additionally it is estimated to considerably intensify past its present state. As of about 11:00 a.m. EDT (1500 GMT) on Thursday, the storm was roughly 255 miles (410 kilometers) southwest of Tampa, Florida, and monitoring north-northeast at 14 mph (23 kph). Most sustained winds measured in at 105 mph (169 kph).

Earlier GOES-16 satellite tv for pc footage, collected when the storm was nonetheless principally targeted over the Gulf of Mexico, additionally supply clear indications of Helene’s progressively rising energy. On NOAA’s Helene-tracking web page, composite imagery from the GOES-East satellite tv for pc mirrors these outcomes, exhibiting the storm following its anticipated trajectory whereas rising stronger.

Some earlier GOES-16 imagery exhibits lightning spiraling within the storm’s arms as properly. In the meantime, a sunrise-to-sunset time-lapse of the hurricane from Wednesday evening (Sept. 25) exhibits it “effervescent, swirling, and slowly strengthening,” CIRA wrote in a separate X submit.

One other certainly one of CIRA’s X posts additionally highlights the best way heat waters nurtured Hurricane Helene within the Gulf of Mexico: Warmth maps reveal the ocean floor temperatures of that physique of water proper round when Helene was about to method. That is of observe as a result of, as consultants have mentioned again and again, local weather change — primarily pushed by human actions like burning coal for affordable energy — fosters the appropriate circumstances for hurricanes to happen extra typically and with better may.
For instance, hurricanes develop in energy as their arms dangle on to moist air and shuffle that moist air inward. Industrial emissions pave the best way for international warming, which suggests hotter air, and hotter air signifies that hurricanes can maintain on to extra water vapor.
And Helene handed over heat Gulf of Mexico waters, proven within the GOES-16 satellite tv for pc’s warmth maps, on its approach towards Florida. That is partially why it was in a position to achieve a lot energy; consultants are thus urging residents of the southeastern U.S. to brace for impression, following related directions of their communities and evacuating if essential.

An advisory put out by NOAA on Wednesday warns of great flash floods in sure zones, depicted within the picture under, in addition to tornadoes and wind speeds better than 80 mph (130 kph). “The mountainous terrain of the southern Appalachians will probably inundate communities in its path with flash floods, landslides, and trigger intensive river and stream flooding,” the group mentioned in an emailed assertion to reporters on Wednesday (Sept. 25).
A Storm Surge Warning applies to areas within the U.S. as far inland as Indiana, however adjoining zones must also stay vigilant as a result of hurricanes have the power to spray out impacts far past their cores.
Energy outages have already begun to happen in affected areas, together with Georgia, Florida and even throughout the Carolinas.
Although scientists imagine Helene will weaken after landfall within the U.S. happens, they stress that robust and damaging winds will proceed to penetrate by way of properly after.
“NOAA’s Nationwide Climate Service is alerting communities that Helene’s flooding rainfall and excessive winds will not be restricted to the Gulf Coast and are anticipated to journey tons of of miles inland,” the group mentioned within the emailed assertion. “Helene is an unusually massive storm, whose windfield extends so far as 275 miles [440 km] from its heart … The main flood danger contains the city areas round Tallahassee, metro Atlanta and western North Carolina, together with Asheville.”
“Gusty winds, mixed with saturated floor, will even increase the chance of falling bushes that may trigger lack of life, property injury, blocked roads, and result in energy outages,” the assertion reads.
