Flood watch continues across southeast Texas through Monday

For much of southeast Texas, including Galveston Island, Montgomery County, and surrounding areas, a flood watch remains in effect through Monday evening due to warnings of excessive rainfall and potential flooding.

Additional rainfall totals of 1 to 3 inches are anticipated, according to the National Weather Service, with isolated areas possibly receiving 4 to 6 inches, especially in the southern section of the region.

During the heaviest downpours, rainfall rates could reach 3 to 4 inches per hour, raising the risk of flash flooding.

Harris County, Fort Bend County, Brazoria County, Chambers County, and coastal and inland areas from the Bolivar Peninsula to Wharton County are just a few of the counties in southeast Texas covered by the watch.

Forecasters warn that excessive runoff could cause floods in low-lying and flood-prone areas and raise water levels in rivers, creeks, and streams. Additionally, urban areas with inadequate drainage systems are more vulnerable.

The meteorological agency warned that "poor drainage and urban areas may experience flooding" and advised locals to stay vigilant as conditions change.

As rain bands move through the area, officials encourage drivers to avoid flooded roads and monitor local forecasts for updates.

The flood watch is expected to remain in effect until Monday night, depending on how the weather plays out.
