Heavy Rainfall

Heavy Rainfall

NASA Satellites have noticed two distinct features in Igor that both indicate how powerful he has become, icy cold, high cloud tops and very heavy rainfall. NASA’s Aqua and TRMM satellites have provided that insight to forecasters who are predicting Igor’s next move as a powerful Category 4 Hurricane. Last week, Igor was a tropical storm who faded into a tropical depression. The National Hurricane Center had forecast that over the weekend Igor would approach more favorable conditions (low wind shear and warm sea surface temperatures) causing it to strengthen into a hurricane and it did. Tropical storm Igor was upgraded by the National Hurricane Center (NHC) in Miami, Florida to a hurricane on Sunday, September 12 at 0300 UTC (Sept. 11 at 11 p.m. EDT) .

The Tropical Rainfall Measuring Mission (TRMM) satellite, which is operated jointly by NASA and the Japanese Space Agency, JAXA captured a good look at Igor a few hours after it reached hurricane status.
