Gulf Moisture Brings Rain and Rising Flash‑Flood Risk to Central and Southeast Texas

An upper-level disturbance is drawing tropical moisture north to produce slow-moving storms that could drop isolated heavy totals early this week.

Overview

  • A weekend pattern change ended weeks of dry heat as scattered afternoon and evening storms developed Saturday and Sunday across Central and Southeast Texas.
  • The National Weather Service placed parts of Southeast Texas at a Level 1 risk for Sunday and upgraded much of the area to a Level 2 risk for Monday, signaling a notable chance of flash flooding in those zones.
  • Model blends show widespread rainfall of about 1 to 2 inches through Wednesday with isolated pockets as high as roughly 4 inches where slow-moving or training storms stall.
  • The extra clouds and rain should keep afternoon highs cooler early next week but forecasts call for a return to hotter, drier conditions later in the week as high pressure and a Saharan dust plume move in.
  • Forecasts remain uncertain at neighborhood scales because storm timing and training are unpredictable, so residents should monitor local forecasts, avoid flooded roads, and expect quick downpours that can produce rapid street and yard flooding.
