Tropical Storm Lorenzo increased in strength and was upgraded to a hurricane with wind speeds of 130 kilometers per hour (80 miles per hour or 70 knots) a few hours before it came ashore about 40 miles south-southeast of Tuxpan, Mexico. Lorenzo weakened after it came ashore, but it was still expected to produce torrential rainfall as it moved slowly inland.
This image was made from data captured by the Tropical Rainfall Measuring Mission (TRMM) satellite at 10:27 p.m. local time on September 27, 2007 (03:27 UTC, September 28). It shows very heavy rain of more than 50 millimeters per hour (2 inches per hour) falling in the eyewall of the hurricane as it was coming ashore in Mexico. Rain rates in the center of the satellite swath are based on the TRMM Precipitation Radar, and those in the outer swath are from the TRMM Microwave Imager. The rain rates are overlaid on infrared data of clouds observed by the TRMM Visible Infrared Scanner.
