On Oct. three at 5:45 a.m. EDT (0945 UTC) NASA’s Terra satellite tv for pc discovered coldest temperatures of strongest thunderstorms (yellow) in Hurricane Walaka had been as chilly as or colder than minus 80 levels Fahrenheit (minus 62.2 Celsius) within the eyewall of the massive, clear eye.

An infrared look by NASA’s Terra satellite tv for pc discovered a hoop of intense storms across the large eye of Hurricane Walaka within the Central Pacific Ocean. Walaka stays a harmful class four hurricane on the Saffir-Simpson Hurricane Wind Scale.
NOAA’s Central Pacific Hurricane Center or CPHC cautioned on Oct. three, “dangerous Hurricane Walaka is intensifying as it moves rapidly north toward the Papahanaumokuakea Marine National Monument and the Johnston Stoll remains in the south quadrant of Walaka.”
A Hurricane Warning is in impact for Johnston Atoll, the Papahanaumokuakea Marine National Monument from French Frigate and Shoals to Maro Reef. A Tropical Storm Warning is in impact for Papahanaumokuakea Marine National Monument from Nihoa to French and Frigate Shoals.
On Oct. three at 5:45 a.m. EDT (0945 UTC) the Moderate Resolution Imaging Spectroradiometer or MODIS instrument aboard NASA’s Terra satellite tv for pc analyzed cloud prime temperatures in infrared gentle. MODIS discovered cloud prime temperatures of strongest thunderstorms ringed across the large eye. Those temperatures had been as chilly as or colder than minus 80 levels Fahrenheit (minus 62.2 levels Celsius). They had been embedded in a big space that circled the attention the place cloud prime temperatures had been as chilly as or colder than minus 70 levels Fahrenheit (minus 56.6 levels Celsius). Cloud prime temperatures that chilly point out robust storms which have the aptitude to create heavy rain.
CPHC famous at 2 a.m. HST (eight a.m. EDT/1200 UTC), the middle of Hurricane Walaka was positioned close to latitude 18.9 levels north and longitude 169.eight levels west. That’s about 150 miles (240 km) north of Johnston Island.
Walaka is transferring towards the north close to 14 mph (23 kph), and it’s anticipated to show towards the north-northeast with a quicker ahead movement later right now and tonight. Maximum sustained winds are actually close to 140 mph (225 kph) with larger gusts. Some gradual weakening is feasible ranging from right now or tonight by way of Thursday, however Walaka is forecast to stay a robust hurricane when it crosses the Papahanaumokuakea Marine National Monument tonight.
CPHC mentioned, “Walaka is forecast to turn toward the north with a slower forward speed starting Thursday. On this forecast track, the center of Walaka will likely reach the Papahanaumokuakea Marine National Monument tonight.”
