Active Weather Alerts

Flood Watch
Issued: 4:25 AM Dec. 25, 2025 – National Weather Service
...FLOOD WATCH NOW IN EFFECT UNTIL 6 AM PST THURSDAY...

* WHAT...Flooding caused by excessive rainfall continues to be
possible. Very heavy rains that occurred earlier in the mountains
continue resulting in water drainage into the Apple and Lucerne
Valleys, causing the potential of flooding to continue into the
overnight hours, even where it is not raining.

* WHERE...A portion of Southwest California, including the following
areas, Apple and Lucerne Valleys, Coachella Valley, Orange County
Coastal Areas, Orange County Inland Areas, Riverside County
Mountains, San Bernardino County Mountains, San Bernardino and
Riverside County Valleys-The Inland Empire, San Gorgonio Pass near
Banning and Santa Ana Mountains and Foothills.

* WHEN...Until 6 AM PST Thursday.

* IMPACTS...Flooding of rivers, creeks, streams, and other low-lying
and flood-prone locations occurred earlier in the day, and will
still continue to be possible throughout the night due to the
excessive rainfall taking longer to work through the local
drainage systems within urban areas. Additional rainfall overnight
may also worsen the threat of this.

* ADDITIONAL DETAILS...
- Several structures are flooded in Wrightwood, due to recent
heavy rainfalls which occurred earlier, with some areas
receiving close to a foot of total rainfall.
Portions of Highway 2 were closed earlier in the day due to
debris flow.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Warnings. Those living in areas prone to flooding should be prepared
to take action should flooding develop.

Avoid flooded roads. Be alert in the mountains for rockslides,
rocks, and debris flows in the road.
