In a matter of minutes Monday morning, communities across southeastern San Diego were transformed into disaster zones: Families fled their homes in chest-deep floodwaters; vehicles were swept downstream as roads became rivers; residents cried for help from their rooftops.
Gusty winds are expected Tuesday in the San Diego County mountains and deserts, plus light rain could fall tonight in coastal and inland valley areas, according to the National Weather Service.
A weak, low-pressure system moving inland Tuesday will cause temperatures to drop through Wednesday, then the mercury will gradually rise heading into the weekend, forecasters said.
The NWS issued a wind advisory that will be in effect from noon Tuesday to 5 a.m. Wednesday in the mountains and deserts.
Winds out of the west are expected to be between 20-30 mph, with gusts possibly reaching 45 mph near desert slopes and through mountain passes, forecasters said.
There is also a slight chance of light rain showers in coastal areas and the western valleys tonight, according to the NWS. Coastal areas have a 20% chance while the western valleys have a 30% chance.
The hottest temperatures of the week are expected Wednesday throughout San Diego County, but relief will arrive this weekend, according to the National Weather Service.
High pressure over Baja California will keep temperatures warm through Friday throughout the county, then temperatures will drop quickly and return to around seasonal average on Sunday, forecasters said.

High temperatures Wednesday are forecast to reach 82 degrees near the coast, 90 inland, 96 in the western valleys, 95 in the mountains and 110 in the deserts.

Temperatures could reach triple digits Monday in the San Diego County deserts, and the mercury will be on the rise all week throughout the region, according to the National Weather Service.
Conditions will be relatively mild west of the deserts Monday, but building high pressure will cause temperatures to rise throughout the county until Friday, forecasters said. By midweek, high temperatures could be 15-20 degrees above average in most areas, forecasters said.
