SAN DIEGO – The second in a pair of weekend atmospheric rivers continued to bring stormy conditions early on the morning of the Martin Luther King Jr. holiday.
The main rain band brought widespread downpour and gusty winds early Monday morning across the San Diego region and more rain is still expected through the course of the day.
Powerful winds toppled trees, knocking them into powerlines and causing power outages early Monday morning in some neighborhoods.
Other people woke up to flooded streets and heavy downpour from a heavy band of rain. The heaviest part of the storm swept the area between 1 a.m. and 8 a.m.
Rain will become more scattered and showery through Tuesday with a quarter-of-an-inch of rain or locally more expected to accumulate on top of already impressive rainfall amounts.

Flooding has been reported along the San Diego River, mainly in Fashion Valley and Mission Valley areas.
The San Diego River reached flood stage (11.3 feet) this morning and is expected to crest this afternoon at 13.2 feet which is just below moderate flood stage (13.5 feet). According to data from the National Weather Service, if it does reach 13.2 feet, it will be the seventh highest crest in history.

High Surf still batters the coastline until Tuesday evening. Another strong swell with waves 8 to 10 feet expected along our beaches.
Winds have mostly subsided along the coast and in the valleys, but gusty westerly winds of 30 mph could pick up again later Monday with strong winds continuing in the mountains.
The next part of this storm will be lowering snow levels. Most of Monday, snow levels have remained fairly high around 6,000 feet, but are expected to drop to 5,000 feet this evening and 4,000 feet early Tuesday morning. A Winter Weather Advisory is in effect for San Diego County mountains as two to four inches of snow and winds of up to 65 mph are expected through Tuesday.
Rain and snow showers look to taper off later Tuesday and then a brief drying period on tap for Wednesday.
