 Flash Flood Watch  Statement as of 8:49 PM CDT on April 28, 2016


... Flash Flood Watch remains in effect from Friday afternoon
through Sunday morning...

The Flash Flood Watch continues for

* a portion of southeast Texas... including the following
Austin... Brazos... Burleson... Colorado... Fort ... Bend...
Grimes... Harris... Houston... Madison... Montgomery... Polk... San
Jacinto... Trinity... Walker... Waller... Washington and Wharton.

* From Friday afternoon through Sunday morning

* unusually moist tropical air will stream into the region Friday
as southerly winds increase. An upper level jetstream will bring
a series of disturbances into the region and should help to
develop showers and thunderstorms Friday afternoon over the
western portions of the watch area then shifting eastward and
northward throughout the region Friday night and Saturday. The
ground is saturated and any storms with high rain rates will
lead to rapid runoff and flooding. The heaviest rainfall threat
should peak Friday night through Saturday afternoon. Additional
rainfall is possible after that and the ground will be saturated
and streams and bayous may already be swollen or flooding.
Widespread rainfall totals through the watch period will likely
average 2 to 4 inches with localized amounts of 5 to 8 inches.
Much of these amounts could come in only a few hours of heavy
rain. As we approach the watch period... confidence in timing
and location will likely improve the focus for where the heavy
rains will fall.

* Streets... bayous... streams and rivers will likely have the
greatest impacts from the heavy rainfall. Motorists and
persons with outdoor activities should stay abreast of the
latest forecasts and have contingency plans for when the heavy
rain arrives.

Precautionary/preparedness actions...

A Flash Flood Watch means that conditions may develop that lead
to flash flooding. Flash flooding is a very dangerous situation.

You should monitor later forecasts and be prepared to take action
should flash flood warnings be issued.
