Red Flag Warning has been extended

The strongest gusts are expected to be around 80 mph near the ridge tops of the San Diego County mountains. For tonight through Wednesday, areas of east to northeast winds will be 15 to 25 mph with gusts to 40 mph with isolated gusts to 55 mph.
Minimum daytime humidity is expected to be around 5 percent with poor overnight recovery.
The strongest and most widespread winds will be Tuesday morning through early afternoon. Winds will not be as strong nor widespread for Tuesday night through Wednesday.
Some good news
The end of the Santa Ana event is finally in sight. Expect gradual cooling later this week as well as the much-anticipated return of onshore flow this weekend.
The lowest daytime humidity on Thursday, except near the coast, is predicted to fall to 5 to 10 percent, but with much weaker winds. Weak onshore flow will return on Friday and begin to spread higher coastal humidity inland.
