Breezy cool winds continued to buffet the North Coast Monday morning after blasting the area during the night, knocking down trees, power lines and causing a gas leak in Bodega Bay, reported emergency officials Monday.

A gust of wind at about 2 a.m. apparently tore part of a roof from a small building at Masons Marina on Westshore Road.

The roof fell onto a propane tank, breaking a valve and causing the leak, reported a Sonoma County fire emergency dispatcher.

Wind gust recordings during the night showed 36 mph at the Charles M. Schulz-Sonoma County Airport, 39 mph in Occidental and 27 mph in Sebastopol.

But in the Bay Area during the night winds whipped much stronger, with one report of 75 mph winds along Ocean Beach in San Francisco breaking out a window, reported Steve Anderson with the National Weather Service.

Several power outages occurred during the night throughout the region, but by Monday morning most had been restored, according to PG&E spokesman JD Guidi.

In Sonoma County there still were 100 customers out in Guerneville and 68 in Healdsburg, said Guidi.

In Mendocino County outages had been reduced to about 300 customers still, Guidi said.

In eastern Sonoma County gusting winds toppled a tree at Sobre Vista Road near Arnold Drive, reported the CHP.

The tree pulled down power lines across the Sonoma roadway.

Guidi said he had no reports of power outages in the area.

Monday's high in Santa Rosa wasn't due to reach 70 degrees. By Wednesday a clash of high and low weather systems overhead was due to cause a sharp swing in temperatures, taking the region from rainy April showers to summer-like 80-plus degrees.
