Warning Description: Fire Weather Warning

Warning Date: 2:52 am MST on May 9, 2008

WarningSum:...Red Flag Warning In Effect From 1 Pm This Afternoon To 8 Pm
Mst This Evening...

Warning Message:The National Weather Service in Tucson has issued a red flag
warning...which is in effect from 1 PM this afternoon to 8 PM MST
this evening. 
An upper level low will start off the day in the Pacific northwest
and make its way east-southeastward through the day today. As it
does so...pressure gradients over Southeast Arizona are expected
to tighten...creating strong and gusty winds. These winds are not
expected to increase until afternoon. This later timing...coupled
with an influx of mid to high level cloudiness...may hinder
mixing and thus not allow winds to reach their full potential.
However...given that isolated stations within the warned area hit
red flag criteria for one or two hours yesterday...when no
tightened pressure gradient existed over the area...this hindrance
may not be enough to keep winds from hitting red flag criteria.
Taking all of this into account...along with the very dry
conditions in place...a red flag warning has been issued for Santa
Cruz and Cochise counties.
A red flag warning means that critical fire weather conditions
are either occurring now...or will shortly. A combination of
strong winds...low relative humidity...and warm temperatures will
create the potential for rapid and erratic fire growth.
Please advise the appropriate officials or fire crews in the
field of the red flag warning today for portions of Southeast
Arizona.
