THEWEATHERMOGIL:: More rain for Houston!
Following torrential and historic Houston area rainfall on Mon., Apr. 18, 2016, Houstonians will need to brace for more rain and flooding. Another thunderstorm outflow boundary (the leading edge of rain-cooled air from a cluster of thunderstorms) is enroute to Houston this morning (Fig. 1 and Fig. 2) and will likely stall to the south of the city later today. Much like the other day, this outflow boundary can serve as a focusing mechanism for new thunderstorm development and allow a track along which storms can move in a repetitive manner.
Although, this outflow boundary seems to be much weaker than Monday’s, saturated ground and high rivers, streams and bayous have primed the area for additional flooding, even with lesser rainfall amounts.
A flash flood watch and numerous river and urban flood advisories and warnings are in effect across the greater Houston area until at least this evening.
There remains a risk for more rainfall as the week unfolds.
Driving remains hazardous in many places. Deaths from the recent flooding have mostly been linked to motorists driving their cars into flooded roadways. The National Weather Service mantra, “Turn around, don’t drown,” should be heeded by all in the Houston area.
