Gusty winds expected in San Diego, high surf continue at coastline
SAN DIEGO (KUSI) – The gusty winds buffeting San Diego County’s mountains and deserts are expected to ease Tuesday evening, but the big waves pounding the coastline will continue into Wednesday afternoon.
A National Weather Service wind advisory issued Monday afternoon is set to expire at 8 Tuesday night. Winds of 20 to 30 miles per hour are expected during the remainder of the advisory period, along with gusts that may reach 60 mph in some areas.
Peak wind gusts recorded overnight reached 64 miles per hour on Volcan Mountain and 57 mph in Harrison Park, according to the NWS.
Forecasters said low pressure was responsible for the gusty wind, cooler daytime temperatures and a slight chance of rain.
"A trough of low pressure moving inland through the Great Basin will bring stronger onshore flow with strong gusty west winds in the mountains and deserts into early evening, cooling with inland high temperatures around 5 degrees below average and a slight chance of sprinkles or light showers early this morning on the coastal slopes of the mountains and the inland valleys,” according to the weather service.
The winds could kick up sand and dust alongside desert roadways, which may make for hazardous driving conditions. The wind might also be strong enough to down tree limbs. Motorists, especially those in high profile vehicles, were urged to use extra caution.
The strong winds combined with a large swell will continue bringing big waves to the beaches. A NWS high surf advisory is set to remain in effect until 2 p.m. Wednesday amid surf of 4 to 8 feet and sets to 10 feet and high tides of 4.8 feet at 9:22 this morning, 4.6 feet at 9:51 tonight and 4.7 feet at 9:54 a.m. Wednesday.
"A large swell from the west-northwest will produce high surf today through Wednesday morning,” according to the weather service. "The swell and surf will diminish late Wednesday.”
Forecasters said the surf and associated rip currents would lead to dangerous swimming conditions. Large waves may break over jetties and sea walls, and minor beach erosion will be possible.
