 Flash Flood Watch  Statement as of 3:33 PM CDT on May 29, 2015


... Flash Flood Watch in effect from Saturday afternoon through
Sunday morning...

The National Weather Service in Houston/Galveston has issued a

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

* From Saturday afternoon through Sunday morning

* a slow moving front will push into southeast Texas Saturday
afternoon through Sunday morning. Thunderstorms are expected to
develop along it and also ahead of the front during the
afternoon. Storms will be slow moving and capable of producing 1
to 2 inches an hour. General rainfall amounts of 1 to 3 inches
will be possible but there may be isolated areas of 5 to 7
inches. Any rainfall amounts over 3 inches will cause flooding
problems.

* Grounds are already saturated so any additional rainfall will
likely run off into bayous... creeks... rivers and lakes. Typical
low lying areas such as underpasses could flood quickly with
rainfall rates of 1 to 2 inches an hour. Additional rainfall
could prolong river flooding across the area. Heavy rainfall
could occur overnight Saturday which will increase The Hazards
of flooding. If flash flood warnings are issued in your
area... do not drive into flooded roads or underpasses. Turn
around do not drown.

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.

1154 PM CDT Friday may 29 2015 


Aviation... 
will probably see some scattered MVFR ceilings and patchy fog develop across 
parts of the area later tonight and early morning. Otherwise 
mainly VFR. Will continue to keep an eye on convection upstream 
for any surprises but feel pretty good to remove most mentions of 
precipitation overnight. Ceilings should lift middle morning and a weak frontal 
boundary will sag in southeast Texas. Expect scattered thunderstorms to develop on both 
this boundary along west/ seabreeze during middle morning hours and 
probably collide across cntl parts of southeast Texas late in the aftn/evng. 
Strong storms and increased rain rates will occur if/where this 
occurs. Another upper disturbance moves in from the north after 
midnight Sunday and could see either continued precipitation or 
redevelopment during the overnight time period. 47 


&& 


Previous discussion... /issued 858 PM CDT Friday may 29 2015/ 
quiet evening across southeast Texas with mostly clear skies. Adjusted probability of precipitation 
down for the rest of the evening and tapered from chance probability of precipitation across 
the extreme northern areas to slight chance elsewhere for the early 
morning hours. Expect cpnvective activity to increase late 
morning/early afternoon tomorrow as a slow moving front approaches 
from the northwest. Still some model differences concerning timing of the 
precipitation tomorrow. Only change for now is to adjust probability of precipitation down a little 
in the morning across southeast areas. Still expect a heavy 
rainfall/flood threat near the boundary beginning at some point in 
the afternoon and continuing into Sat night. 33
