 Flash Flood Warning  Statement as of 4:40 PM MST on August 7, 2008


... A Flash Flood Warning remains in effect until 545 PM MST for
southwestern Cochise County...

At 429 PM MST... National Weather Service Doppler radar continued to
indicate a thunderstorm producing flash flooding. This storm was
located near Huachuca City... or near Sierra Vista... moving northwest
at 6 mph. Current radar trends indicate that rainfall rates have
begun to fall... however... continued rainfall over the area will only
add to the already saturated conditions. Motorists as well as those
living in low lying and flood prone areas are urged to use caution
and continue to monitor conditions... as flash flooding can occur
with little or no advance warning.

This includes the following streams and drainages...
San Pedro river... babocomari river and Slaughter house wash.

Excessive runoff from heavy rainfall will cause flooding of small
creeks and streams... highways and underpasses. Additionally... country
roads and farmlands along the banks of creeks... streams and other low
lying areas are subject to flooding.

Area forecast discussion 
National Weather Service Tucson Arizona 
200 PM MST Thursday Aug 7 2008 


Synopsis...favorable conditions for strong thunderstorm development 
today and tonight...otherwise sufficient moisture will remain over 
the area for a daily chance of showers and thunderstorms into next 
week. 


&& 


Discussion...strong convective development this afternoon with low 
level moisture convergence...decent instability and shear. As stated 
this morning during the update...organized convection initially near 
the border that spreads into much of Santa Cruz and eastern Pima 
counties and subsequently the Tohono Oodham Nation during afternoon 
and evening hours. Isolated action kicking in for southeast Pinal 
and Graham counties as well. Middle shift had a nice trend showing 
this...we put out a morning update to tweak and emphasize this a bit 
more. Also severe weather potential statement out for stronger storms today. Concern includes both 
severe and flash flood potential. 


If we do go off over a wide enough area today and tonight (which is 
starting to be the case)...the flow is not such to reset right 
away...so would see somewhat of a down day Friday. If we don't have 
widespread enough convection then Friday should be a strong 
thunderstorm day. Otherwise should be a good weekend for storms with 
a Standard forecast to start the week as sufficient moisture and 
instability hang in for typical early August weather. 


&& 


Aviation...scattered thunderstorms this afternoon and evening with 
locally heavy rainfall and strong outflows. Aviation discussion not 
updated for taf amendments. 


&& 


Twc watches/warnings/advisories...none.
