    Parts of San Diego County will be swept by strong, potentially damaging winds Wednesday as a low pressure system moves into the area, according to the National Weather Service. 

SAN DIEGO (CNS) - High winds out of the north whipped through San Diego County Thursday, giving people reason to hang tight to their hats and creating potential for property damage but causing no reported problems.

The gusty conditions, caused by a strong low-pressure system that moved over the region Wednesday night, turned out to be less severe than initially expected, prompting the National Weather Service to rescind the high-wind warning it had instituted for area mountain locales and replace it with a lower-level wind advisory.

That reduced alert status -- which predicts sustained air currents of 15 to 30 mph, with gusts up to 50 mph -- is slated to remain in effect in the East County highlands and deserts until 10 a.m. Friday. Until then, the winds still could topple trees, power lines and unsecured outdoor objects while posing difficulties for motorists, especially those driving "high profile" vehicles, the NWS advised.

A wind advisory for San Diego-area inland valleys, meanwhile, was canceled, as well. Still, breezier-than-normal conditions, with gusts up to 30 mph, were expected to prevail in those areas through late Friday morning, forecasters said.

THIS IS A STORY UPDATE. For an earlier version, read below.

SAN DIEGO (CNS) - Strong, potentially damaging winds out of the north blew across San Diego County Thursday, especially in the mountains.

The change of weather stems from a strong upper level low pressure system that moved south into the area Wednesday night, according to the National Weather Service. The agency issued a high wind warning for the mountains until 2 p.m. Friday.

A less serious wind advisory is in effect in coastal, valley and deserts areas until 2 p.m. Friday.

"Winds will mainly be confined to the ridge tops and northeast portions of the mountains today, then turn ... and spread into the coastal slopes and foothills tonight," the Weather Service advised.

In the mountains, sustained winds of 20-40 mph with gusts up to 60 mph were expected. Elsewhere in the county, winds of 15-20 mph, with gusts up to 45 mph, were likely, according to the Weather Service.

"Wind gusts this strong are capable of downing trees and power lines, and blowing over unsecured outdoor objects," the Weather Service advised.

"These winds will also create hazardous conditions for high profile vehicles."

Visibility will be reduced to less than 3 miles in areas with blowing dust, according to the agency.

The windy weather also prompted a gale warning for local boaters. A gale warning is in effect until 4 a.m. Friday for coastal waters off San Diego County.

Boaters should be prepared for rough seas due to short-period wind waves from the northeast and a longer period westerly swell, according to the Weather Service.

"Operating a vessel in gale conditions requires experience and properly equipped vessels. It is highly recommended that mariners without the proper experience seek safe harbor prior to the onset of gale conditions," the Weather Service advised.
