533 FNUS55 KPSR 170744 FWFPSR Fire Weather Planning Forecast for Southwest and South-Central Arizona and Southeast California National Weather Service Phoenix AZ 1244 AM MST Sat May 17 2025 ...ELEVATED FIRE DANGER THIS AFTERNOON AND EARLY EVENING ACROSS ARIZONA... .DISCUSSION... Wind speeds will increase substantially beginning this afternoon with gusts 25-35 mph becoming common. For the eastern districts into portions of southwest Arizona, the combination of the gusty winds and humidity values falling into a 10-15% range will yield an elevated fire danger. While wind speeds will only be slightly weaker Sunday, humidity values only falling into a 20-25% range will preclude a greater threat. Correspondingly, poor to fair overnight recovery of 20-50% will improve closer to a 40-60% range Sunday. Note...Additional Fire Weather Forecast information can be found in the Area Forecast Discussion. See product PHXAFDPSR.
