There remains a Moderate (Level 2 of 4) with some pockets of Major (Level 3 of 4) Risk of heat-related illness across Deep South Texas and the Rio Grande Valley today. Be sure to drink plenty of water if spending time outdoors.

A Fire Danger Statement is in effect this afternoon and early evening for all of Deep South Texas, excepting the coastal counties and islands. Southeasterly winds between 15 and 25 mph are expected, with gusts up to 35. Humidity could get as low as 15%, especially in the Western Ranchlands. Avoid outdoor burning and properly discard cigarettes.

We continue to monitor Tropical Depression Two, located over the northeastern Gulf. The area of low pressure currently has a well-defined circulation and wind speeds up to 35 mph. It is forecast to become a Tropical Storm later today and is expected to move west-northwest or west towards the Louisiana and Upper Texas Coast. At this time, no direct impacts are expected for Deep South Texas, but we could see increased rip currents, dangerous surf, and minor coastal flooding later this week.

Hot and breezy at local beaches today with a MODERATE RISK of rip currents in the surf zone.

Hot and mainly rain-free conditions will continue through the first half of the weekend. However, there is a low chance of showers and thunderstorms by late week. Temperatures are forecast to climb each day bringing an increased risk of heat-related illness through the week. Be sure to practice heat safety - learn more at weather.gov/heat
