...CRITICAL FIRE WEATHER CONDITIONS EXPECTED TODAY INTO THIS
EVENING IN THE MOUNTAINS AND FOOTHILLS...
...CRITICAL FIRE WEATHER CONDITIONS POSSIBLE SATURDAY AFTERNOON
ACROSS THE HIGH MOUNTAINS AND NORTH PARK...
Fire weather conditions will remain elevated in the mountains and
foothills this afternoon and evening due to gusty southwest
winds, low humidity and continued warm temperatures. A dry cold
front will then bring strong northwest winds this evening,
continuing the critical fire weather conditions due to low
humidity and a wind shift into the early evening.
Drier humidity is expected Saturday with weaker northwest winds,
but could be right around criteria. The possible critical fire
weather conditions will most likely affect North Park and the
higher mountains.
