Brace yourselves for more wet weather since a historic winter season isn’t quite finished delivering rain, snow and windy conditions that have toppled trees across San Diego County.

The inclement weather made for a messy morning commute Wednesday as the first wave of a storm passed through the region. The storm dumped measurable rain on the majority of San Diego County and brought more snow to mountain communities.

As of 6:30 p.m., the highest three-day rainfall totals for each microclimate were:

Coastal
Carlsbad received the most rain with 1.07 inches, followed by .94 inches in Vista and .75 inches in Oceanside.

The rain is gone, for now, but strong winds and low temperatures are sticking around. NBC 7's Dana Williams has the story.

Inland Valleys
Skyline Ranch, with an elevation of 2,130 feet, received 2.24 inches of rain, so far. Most areas saw an inch of rain or more. Here are some other inland rainfall totals, in inches:

Before the weather cleared, it was creating some chaos across San Diego.

In Poway, a giant pine tree crashed into a two-story home before 7 a.m. Wednesday. The homeowner woke up to what he thought was an earthquake but found the tree through his bedroom ceiling. He wasn't injured but said he would have to find a hotel to stay at while his home is renovated.

In the mountain community of Descanso, a large tree fell onto a kindergarten playground and a shed that houses the school's electrical equipment. The Mountain Empire Unified School District called San Diego Gas & Electric to assess the facility and determine if the area was safe.

Gusty winds picked up overnight when a wind advisory goes into effect until 6 p.m. Wednesday. Winds along the coast are expected to be in the 20 to 30 mph range with some gusts up to 50 mph. In the deserts, winds in the 25 to 45 mph prompted a high wind warning from 2 p.m. Tuesday to 10 p.m. Wednesday. Some gusts could reach 75 mph, the NWS said.

Snow levels could be as low as 2,000 feet on Wednesday evening, according to NBC 7 Meteorologist Dagmar Midcap. Up to 2 feet of snow is possible at elevations near 5,000 feet by the time the storm clears the area on Thursday, Midcap said.
