Statement as of 6:52 PM CDT on August 19, 2008

... Flash Flood Watch now in effect until 4 am CDT Wednesday...

The Flash Flood Watch is now in effect for

* a portion of deep south Texas... including the following
areas... Hidalgo... Jim Hogg... Starr and Zapata.

* Until 4 am CDT Wednesday

* a broad low pressure area in the middle layers of the atmosphere
over north central Texas... combined with deep tropical moisture...
will produce scattered to numerous showers and thunderstorms
over the western portions of deep south Texas through early
Wednesday morning. Additional rainfall amounts of 1 to 3 inches
are possible with the shower and thunderstorm activity through
early Wednesday morning with some isolated areas possibly
receiving 2 to 4 inches of additional rainfall. Additional
flooding problems may occur across the western portions of deep
south Texas due to the potential heavy rains... especially in
areas already saturated by rainfall over the past several days.

* Remember... when water covers the Road... turn around... don't
drown. Motorists should never attempt to cross any flooded
roadways.

A Flash Flood Watch means that inland freshwater flooding is
possible. Residents living in flood prone areas should take action
to protect property.
