| Area Forecast Discussion National Weather Service Brownsville TX 607pm CDT Wednesday Mar 11 2026 .FIRE WEATHER/MESOSCALE UPDATE FOR A CRITICAL FIRE WEATHER RISK THIS AFTERNOON/EVENING... Issued at 410pm CDT Wednesday Mar 11 2026 We've decided to issue a Red Flag Warning for all of Deep South Texas with the exception of the island till 8pm CDT due to the critical risk for fire weather. Following the passage of a dryline, relative humidity values have fallen precipitously across the region. In it's wake, breezy northwest winds have also developed 10-20 mph gusting as high as 30 mph in spots. Given the low relative humidity values married with breezy northwest winds, record to near record-breaking heat from strong compressional heating, and an ongoing drought (i.e. D2 Severe Drought to D4 Exceptional Drought), a critical fire weather risk is present across the region. Additionally, The Texas A&M Forest Service has highlighted the area under a high fire danger threat with pockets of very high across the Lower Valley (i.e. Cameron/Willacy counties) and the northern parts of Brooks into Kenedy counties. Make sure to exercise fire weather safety. Issued at 1213pm CDT Wednesday Mar 11 2026 A cold front is expected to pass through Deep South Texas tonight, which will bring slightly cooler and much drier air to the region. This drier air, combined with the ongoing D2 to D4 drought, will create elevated fire concerns. A Fire Danger Statement is in effect through this evening, and a Fire Weather Watch is in effect for the central and eastern counties of the CWA (County Warning Area) for tomorrow following the frontal passage. Depending on wind speeds and how low the humidity gets behind the front, a Fire Danger Statement or Red Flag Warning may be needed tomorrow. Unfortunately, there does not appear to be any drought relief next week, as precipitation chances remain below 10 percent. Tomorrow's high temperatures will be below seasonal averages in the mid 70s with lows in the mid-to-upper 40s. A warming trend commences on Friday and will continue through the weekend with highs topping out in the low to mid 90s. Another system moves through Sunday night into Monday which will bring a slightly stronger front to the region. This front will keep high temperatures in the mid-70s for a few days Monday and Tuesday, and possibly create more fire weather concerns for early next week. There is also high risk of life-threatening rip currents at area beaches tonight and tomorrow. Marine Issued at 1213pm CDT Wednesday Mar 11 2026 A Small Craft Advisory has been issued for 06z tonight through 06z Friday. Adverse marine conditions are expected on the Bay and on the Gulf waters. Conditions should improve for the start of the weekend, but SCEC conditions (Small Craft Should Exercise Caution) are possible starting Sunday as the pressure gradient tightens ahead of an approaching system. More Small Craft Advisories may be needed Monday around the time of the frontal passage. Conditions should become more favorable Tuesday into Wednesday. NOAA Brownsville TX Office: Watches - Warnings - Advisories TX...Red Flag Warning until 8pm CDT this evening for TXZ248>255-351- 353>355. Fire Weather Watch from Thursday morning through Thursday evening for TXZ250-251-253>255-351-353>355. High Rip Current Risk through Thursday evening for TXZ451-454- 455.
