NASA - National Aeronautics and Space AdministrationGreenbelt, MDNASA-NOAA’s Suomi NPP Satellite offered a night-time and infrared have a look at the Atlantic’s newest hurricane that exposed the ability underneath the clouds. NASA’s GPM additionally offered a have a look at the rainfall being generated by Hurricane Irma.

After forming within the japanese Atlantic Ocean on Wednesday tropical storm Irma strengthened and have become a robust class three hurricane on Thursday August 31st, 2017.

On Sept. 1st at 0347 UTC (Aug. 31 at 11:47 p.m. EDT) the VIIRS instrument aboard NASA-NOAA’s Suomi NPP satellite tv for pc captured a night-time picture of Hurricane Irma within the Atlantic Ocean that confirmed a decent circulation. (NASA/NOAA/UWM-CIMSS, William Straka III)

Two Suomi NPP Satellite Views

On September 1st at 0347 UTC (August 31st at 11:47pm EDT) the Visible Infrared Imaging Radiometer Suite (VIIRS) instrument aboard NASA-NOAA’s Suomi NPP satellite tv for pc captured a night-time picture of Harvey that confirmed the middle of circulation had moved again into the Gulf of Mexico.

On Sept. 1st at 0347 UTC (Aug. 31 at 11:47 p.m. EDT) the VIIRS instrument aboard NASA-NOAA’s Suomi NPP satellite captured a night-time infrared image of Hurricane Irma in the Atlantic Ocean that showed powerful thunderstorms around the eye. (NASA/NOAA/UWM-CIMSS, William Straka III)

On Sept. 1st at 0347 UTC (Aug. 31 at 11:47 p.m. EDT) the VIIRS instrument aboard NASA-NOAA’s Suomi NPP satellite tv for pc captured a night-time infrared picture of Hurricane Irma within the Atlantic Ocean that confirmed highly effective thunderstorms across the eye.

Infrared knowledge from the VIIRS instrument aboard confirmed highly effective thunderstorms across the eye have been cloud prime temperatures have been as chilly as 190 kelvin.

The colder the cloud tops, the upper they’re within the troposphere, and the extra highly effective the storms. NASA analysis has proven that storms with cloud prime temperatures that chilly have the potential to generate heavy rainfall.

Finding Irma’s Heaviest Rainfall

That heavy rainfall was confirmed by the Global Precipitation Measurement mission or GPM core satellite tv for pc.

Hurricane Irma was shifting west-northwestward with winds of about 115 mph (100 knots) when the GPM core Observatory satellite tv for pc noticed it on September 1st at 1:47am EDT (0547 UTC). Data collected by GPM’s Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) devices confirmed the areas and depth of heavy precipitation throughout the hurricane. 

GPM’s Radar (DPR Ku band) discovered highly effective convective storm in a band of rain on Irma’s northern facet was raining down at a fee of virtually 6.Three inches (159 mm) per hour.

GPM’s radar (DPR Ku Band) confirmed the peak and the Three-D rainfall construction of highly effective storms spiraling round hurricane Irma. DPR confirmed that storm tops have been reaching heights of over 9.6 miles (15.5 km) within the band of highly effective convective storms north of the hurricane’s middle. GPM is a joint mission between NASA and the Japanese house company JAXA.

On Sept. 1st at 1:47 a.m. EDT (0547 UTC) GPM core observatory found a band of rain on Irma's northern side was dropping rain at a rate of almost 6.3 inches (159 mm) per hour where storm tops were reaching heights of over 9.6 miles (15.5 km). (NASA/JAXA, Hal Pierce)

Irma’s Location and Strength on Sept. 1st

The National Hurricane Center (NHC) mentioned that at 11:00am EDT (1500 UTC) on September 1st that Irma was present process an eyewall alternative cycle.  The small eye was turning into much less distinct, with each microwave and visual imagery indicating the presence of a forming outer eyewall.

The middle of Hurricane Irma was situated close to 18.5 levels north latitude and 27.eight levels west longitude. That’s about 1,580 miles (2,540 km) east of the Leeward Islands. Irma was shifting towards the west-northwest close to 13 mph (20 kph).  A flip towards the west is predicted by tonight, adopted by a flip towards the west-southwest on Saturday, September 2nd.

Maximum sustained winds are close to 110 mph (175 kph) with larger gusts.  Fluctuations in power, up or down, are doable in the course of the subsequent few days, however Irma is predicted to stay a robust hurricane by means of the weekend. Hurricane-force winds lengthen outward as much as 15 miles (30 km) from the middle and tropical-storm-force winds lengthen outward as much as 90 miles (150 km).

The estimated minimal central stress is 972 millibars.

The NHC predicts that hurricane Irma will slowly intensify whereas heading towards the west-northwest. Irma is predicted to have winds of over 123 mph (110 knots) throughout the subsequent 5 days. This would make Irma a powerful class Three hurricane on the Saffir-Simpson hurricane wind scale. There is a few uncertainty about the long run course of Irma’s motion.
