SAN DIEGO (CNS) - A trough of low pressure digging down on the west coast sent strong westerly winds sweeping across the mountains and deserts of San Diego County today.
The National Weather Service issued a high wind warning for mountain and desert areas effective until 9 a.m. Tuesday, saying the winds were likely to cause areas of blowing dust and sand in some areas, reducing visibility and making driving hazardous.
Sustained winds of 25 to 35 miles per hour gusting up to 60 mph were blowing, along with isolated gusts up to 75 mph, according to an NWS advisory.
Later today, off the coast, higher seas and occasional strong west to northwest winds were expected.
The weather service issued a small craft advisory from 6 tonight to 10 p.m. Tuesday.
``Combined seas will reach 9 to 11 feet in mainly the outer coastal waters, and the winds will be 15 to 25 knots with gusts to 30 knots at times,'' according to an NWS advisory. ``Seas will be rough and choppy due to the combination of the fresh west-northwest swell with a period of only 8 to 10 seconds, a long-period south swell and the wind waves. This will create a hazard to small craft in the coastal waters.''
