HOUSTON - Rain is expected to begin moving into southeast Texas Friday afternoon, with on-and-off pockets of heavy rain moving through between Saturday and Monday morning.
Isolated flash flooding is possible this weekend where the rainfall is hardest and longest-lasting.
Coastal areas may see the greatest rainfall totals, since that is where the highest atmospheric moisture will be. Six to eight inches of rain is certainly possible, with higher isolated amounts.
The wet weekend is being caused by a potent disturbance that will stall over northern Mexico on Friday and linger until Monday, when it finally exits to the east of Texas ant takes the rain with it. The disturbance will tap into abundant Gulf of Mexico and Pacific moisture as fuel for the heavy rain.
Currently, no flash flood watches have been issued for the region. Watches will likely be issued on Friday or Saturday, as the system continues to develop.
