Weather Houston has a First Alert Weather Day in place for Monday as tropical moisture and a weak front are set to send rounds of heavy rain across East Central Texas through Wednesday. The wet pattern begins Sunday, but the biggest concern rises after the morning drive Monday, when rain coverage is expected to jump and the flood risk starts to sharpen.
By Monday through Wednesday, forecasters expect the front and any outflow boundaries to help focus the heaviest downpours. Some spots closer to the coast could see rainfall totals approach 6 inches or more by Wednesday, while localized flooding remains possible in the Brazos Valley where the hardest rain falls.
The setup comes from deep tropical moisture tied to the remnants of Cristina in the Pacific, which has moved into the Gulf, combined with a weak frontal boundary sliding through Texas late this weekend and into early next week. That pairing is expected to keep buckets of rain falling across the area through at least Tuesday, with afternoon rain coverage higher on Sunday as moisture streams in from the Gulf.
The one thing still unresolved is where the worst water problems will land. The low tropical development of the system means it is not expected to organize much, but it still has enough moisture to fuel a soaking stretch for Texas. Details should become clearer as the weekend ends, and the places that get stuck under repeated rain bands will be the ones to watch first.
For now, the message is simple: the rain threat is real, the timing is set, and Monday is the day to pay closest attention in Weather Houston.
