Beta Feeder Band Could Dump 1-2″ Per Hour; Street Flooding Possible
Feeder Band Approaching from South
Jeff Lindner, Harris County Meteorologist noted at 1:35 PM that a feeder band of heavy rainfall from Tropical Storm Beta is moving from northern Brazoria and northern Galveston Counties into southern Harris and Fort Bend Counties.
Lindner says that “rainfall amounts of 1-2 inches per hour will be possible under this band for the next 1-2 hours. This may lead to street flooding in typical areas of poor drainage.” Rates above 2 inches per hour will generally flood streets.
According to Space City Weather, currently, it looks like these storms may produce 2 to 3 inches of rain total as they slowly progress northward, so they could impact the afternoon and evening commute home.
Beta Weakening As It Approaches Landfall
The center of Beta is nearing landfall on the TX coast near Matagorda Island with 45mph winds.
At its 1 p.m. update, the National Hurricane Center said the storm weakened this morning. Sustained winds dropped from 50 to 45 mph. The storm’s central pressure also rose from 996 to 999 mb, another sign of weakening. Welcome signs!
Heavy Rainfall From Training Feeder Bands Will Continue
Heavy rainfall threat in bands to the east and northeast of the center will continue into tonight and Tuesday. “This threat will not subside until the center of the circulation is east of the area on Wednesday,” says Lindner.
Lindner further expects “No significant changes to the rainfall totals. Amounts of 4-8 inches are most likely with isolated higher amounts. But these higher totals will likely be strongly correlated to training feeder bands.”
