The National Weather Service in Houston has issued a Flash Flood Watch for portions of Southeast Texas. This watch is in effect late tonight through the evening hours tomorrow. A round of heavy rainfall is expected tonight as a non-tropical area of low pressure moves onshore. Saturated soils, abundant moisture levels, and slow movement of the rain could result in localized flooding. We’re not expecting widespread or significant flooding tonight. Still, if someone receives 3 inches of rain in one hour, that’ll cause some short-term flash flooding. Remember that it is difficult to determine the height of water flowing over a road. Turn around, don’t drown!

* Slow moving thunderstorms are expected to develop over the watch
area producing periods of heavy rainfall. Deep tropical moisture
will spread over the region tonight and Monday fueling the
development of storms beginning around midnight. These storms
will be capable of 2 to 3 inch per hour rainfall rates given the
moist environment and slow movement. Rainfall totals of 1 to 3
inches can be expected with isolated totals of 5 to 6 inches.
Some areas that received moderate to heavy rainfall today will
be more prone to runoff and street flooding. The storms should
weaken by late Labor Day afternoon.

* Primary impacts will likely be street flooding and low water
crossings. Minor flooding is possible of streams and bayous in
the area though any flooding would likely be limited to just the
smaller watersheds.
