Stay weather-aware this week as daily downpours may lead to street flooding. Houston is under a flood watch through Wednesday morning. Most areas will pick up 2 to 3 inches of rain, but there could be some locally higher totals near 8 inches!

Through Wednesday

Moisture headed to southeast Texas:

I’m monitoring a low-pressure system moving through Mexico; it is expected to funnel deep, rich tropical moisture into the area. The low-pressure system currently has a 30% chance of developing into a tropical system, but regardless of development, it will still draw in tropical moisture into southeast Texas at least through the end of the week.

Monday through Wednesday the tropical moisture will combine with a slow-moving cold front. That will help bring waves of rain through the middle of the week.
