The National Weather Service in Phoenix has issued a red flag warning... which is in effect until 5 PM MST /5 PM PDT/ this afternoon... due to strong winds... low humidity and high fire danger.
A cold front was located between Yuma and Phoenix early this morning with very dry air and strong winds throughout most of southeast California. This system was moving east and will cause rh to drop rapidly in the Phoenix area by around mid day. Expect 20 to 30 mph winds with gusts to near 35 mph. In addition... humidity will drop rapidly behind the front... with rh values falling to less than 15 percent. This combination of strong winds and low rh will overspread the entire area by early this afternoon with widespread hazardous fire weather conditions likely.
Please advise the appropriate officials and fire crews in the field of this red flag warning.
