Tropical Storm Edouard Impacting the Northwestern Gulf Coast; Hazardous Heat expands in the East

Tropical Storm Edouard will impact the northwestern Gulf Coast through Wednesday with gusty winds, storm surge, and heavy rainfall. Flash and river flooding will be possible, especially in southeastern Texas. Hazardous heat will expand across the central and eastern U.S. by mid-week, and daily chances for severe thunderstorms are expected from the eastern Great Lakes to the Mid-Atlantic this week.

Fig. 15. The combined infrared satellite imagery and regional radar reflectivity mosaic from 2300 UTC 16 July to 0200 UTC 17 July 2003 shows Claudette as it became increasingly disorganized over far southwest Texas. Satellite imagery suggests that the middle and upper level cloud structure became less symmetrical with time as the system weakened and dry air began to entrain into the circulation from the south. Plots of the regional surface observations reveal that Claudette’s low level circulation was becoming displaced from the circulation aloft as it began rapidly moving west-northwest into northern Mexico. In addition, thunderstorms can be seen initiating over the Serranias del Burro Mountains in northern Coahuila, Mexico. This convection trained north over Terrell County, and resulted in heavy rainfall and flash flooding.
