Tropical storm Humberto, located in the eastern Atlantic Ocean, had little deep convection and was classified by the National Hurricane Center (NHC) as a post-tropical cyclone on September 14, 2013. On September 16, 2013 Humberto was having bursts of strong convection and was again classified a tropical storm.

 

Humberto was viewed during the daytime by the TRMM satellite on September 15, 2013 at 1652 UTC (12:52 PM EDT) and on September 16, 2013 at 1557 UTC (11:57 AM EDT). These TRMM orbits show the significant changes that occurred within Humberto's in less than 24 hours. In the first orbit on September 15, 2013 Humberto's center of circulation was rain free and only contained a small area of convective rainfall that was located well to the north of Humberto's surface location. Areas of strong convective rainfall were associated with rebounding Tropical Storm Humberto when TRMM viewed the same area on September 16, 2013.

 

Humberto is forecast by the National Hurricane Center (NHC) to maintain tropical storm intensity while moving toward the north-northeast over the open waters of the northeastern Atlantic Ocean. Humberto is forecast to again become a post-tropical low in about 96 hours.
