Widespread showers and thunderstorms are expected today, which will produce heavy rainfall with 1.5 to 3.0 inches/hour and higher rain rates. Further rounds of rain will cross the region from today to early Wednesday. A Flood Watch is in effect area-wide. A lull in rainfall rates/coverage is anticipated Wed before a more intense wave of tropical rainfall arrives Thu. The flooding risk will increase with each day and the flood watch may be extended. Coastal flooding will be possible later in the week in response to coastal low pressure moving inland.
Multiple rounds of heavy rainfall are expected as a surge of deep tropical moisture moves into the area and interacts with a stalled frontal boundary. Rainfall amounts of 3 to 6 inches, with localized heavier amounts of up to 10 in are possible now until Wednesday Another round of heavy rain is expected Thu/Fri which may trigger an extension of the watch.
Multiple rounds of showers and storms will develop each day as a stalled frontal boundary absorbs a very humid air mass streaming into the region. Flooding risk will increase into Tuesday into Wednesday as rain totals accumulate.
Several rounds of widespread heavy rains are expected from this afternoon through early Wednesday. A second round of heavy tropical-like rainfall is then possible again late in the week as a weak low crosses the area. A flash flood risk will exist Sunday afternoon - late Tuesday. Rain totals of 3-5 inches are expected with higher amounts in some spots. Another 3 to 5 inches of rainfall will be possible Thu/Fri. The flash flood risk could continue into the end of the week, depending on the rainfall totals from Sun-Wed.
A trough of low pressure located over northeastern Mexico continues to produce disorganized shower and thunderstorm activity. Development is not expected during the next day or so while the trough remains inland and drifts generally northward over northeastern Mexico and southern Texas. The system is then forecast to move northeastward and could re-emerge over the northwestern Gulf of America late Tuesday or Wednesday, where environmental conditions may support some development around midweek.
