Tropical Depression TWO-E was upgraded to tropical storm Boris yesterday at 1800 UTC (11AM PDT) but Boris weakened to a tropical depression after going ashore in Mexico. The TRMM satellite passed above tropical depression Boris on June 4, 2014 at 1457 UTC and collected data used in this rainfall analysis. TRMM rainfall data are shown overlaid on a GOES-EAST enhanced infrared/visible image received at 1445 UTC. TRMM's Microwave Imager (TMI) data show that Boris was still dropping light to moderate rain over southern Mexico in the area of the Gulf Of Tehuantepec. Click on this animation to see a

As predicted, yesterday afternoon a low pressure center south of the Gulf of Tehuantepec was classified as tropical depression TWO-E by the National Hurricane Center (NHC). The TRMM satellite passed over the area on June 3, 2014 at 0602 UTC (11PM PDT June 2, 2014) providing data for the TRMM rainfall analysis shown in brighter shades overlaid on an enhanced GOES-EAST 0615 UTC image. TRMM's Microwave Imager (TMI) instrument had a good view of TWO-E's center and indicated that rain northeast of there was falling at a rate of over 61 mm/hr ( about 2.4 inches). An NHC discussion said of tropical
