Flash Flood Watch

Statement as of 3:01 PM CDT on May 24, 2015

Expires 8:00 PM EDT on May 25, 2015


... Flash Flood Watch in effect from Monday morning through Monday
evening...

The National Weather Service in Houston/Galveston has issued a

* Flash Flood Watch for a portion of southeast Texas... including
the following counties... Austin... Brazos... Burleson...
Colorado... Grimes... Harris... Houston... Liberty... Madison...
Montgomery... Polk... San Jacinto... Trinity... Walker... Waller
and Washington.

* From Monday morning through Monday evening

* the next upper level disturbance will move into central Texas on
Monday. Expect this disturbance to trigger another shower and
thunderstorm complex to our west. This system should be moving
into western parts of the area toward mid morning and across the
remainder of the region through the afternoon hours. Upper level
conditions are again favorable for training strong storms. There
is some uncertainty just how fast the system will move out and
some locations could see precipitation continue into the
evening. In general... expect 1 to 3 inch rainfall amounts in
the watch area... especially north of Interstate 10 where
conditions are more favorable for the higher amounts. Localized
higher totals are possible where training cells occur... and also
if the event drags on into the evening hours. This watch will
need to be expanded in time if it does.

* Impacts... the ground remains saturated and additional heavy rain
in a short time period will run off and create flash flooding
and additional rises on already swollen rivers.

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.

This is where the minor injuries and more significant damage occurred. Most of the
damage was EF0, however one location had complete roof removal and evidence of some
interior wall compromise consistent with EF1 damage. 12 story glass facade building
just south of the complex along bissonnet St. Had several north-facing windows blown
out indicative of rotation with the damaging winds.
