FIRE WEATHER…
North to northeast winds will develop this morning below the
Cajon and Morongo passes and the Santa Ana Mountains at 15 to 25
MPH with local gusts 35-40 MPH, spreading into the San Gorgonio
pass by late morning as they turn more northeast to easterly and
weaken slightly. Highest gusts will be near the Cajon Pass and
the northern Santa Ana Mountains and foothills. Relative humidity
will fall to 12-20 percent, lowest in the Inland Empire, by mid
afternoon. This will create areas of elevated fire weather
conditions. Moderate humidity recovery is expected in most areas
tonight, though the windy corridors will remain fairly dry with
maximum humidity of only 20-30 percent.

The east to northeast winds will continue into Monday morning with
widespread speeds of 15-25 MPH and local gusts of 35-40 MPH near
the coastal foothills and below the passes and canyons. Humidity
will continue to fall through Monday afternoon with widespread minimum
values around 10 percent, but winds will weaken. A few hours of
critical fire weather conditions are expected on late Monday
morning into the early afternoon along the coastal foothills.

Continued breezy through Tuesday morning with a further weakening of
the winds by afternoon. Widespread humidity around 8-12 percent is
expected again Tuesday afternoon, along with well above average
temperatures into the 90s in many areas, continuing an elevated
fire weather condition.

A brief respite develops Wednesday as onshore flow tries to develop,
but another offshore push develops on Thursday. Gusty offshore winds
are likely again along with single digit humidity and much above
average daytime temperatures into Friday. This event still has the
potential to be stronger than the one earlier in the week, but
confidence in exact strength is low.

POSSIBLE SCE SHUT OFF AREAS DUE TO EXPECTED HIGH WINDS.
