Tsunami waves generated from the underwater volcanic eruption near Tonga were expected to impact the San Diego County coast Saturday morning, which also received a band of light rain, the National Weather Service said.
“Widespread inundation is not expected,” forecasters said. “However, a tsunami capable of producing strong currents that may be hazardous to swimmers, boats, and coastal structures is expected.”
No evacuation orders were in place in San Diego County.
A high surf advisory was issued until 2 p.m. Saturday for San Diego County coastal areas. A west swell of 4 feet at 14-15 seconds was expected to produce elevated to high surf Saturday. Surf of 4-7 feet was expected. Moderate to strong rip currents were predicted at all beaches.
A band of light rain due was slowly moving north and covered most of western San Diego County, with most areas receiving a few hundredths of an inch of precipitation.
There were also locally gusty easterly winds from the coastal mountain slopes west into some of the valleys, with a local gust of 60 mph at Hellhole Canyon at around 6 a.m., and a few other stations with gusts over 50 mph.
High temperatures along the coast Saturday were predicted to be 67-72 degrees with overnight lows of 50-55. Western valley highs will be 67-72, with highs of 61-66 near the foothills and overnight lows of 49-55. Mountain highs were expected to be 53-59 with overnight lows of 40-47. Highs in the deserts will be 68-73 with overnight lows of 46-55.
Light showers were also possible Monday evening through Tuesday morning, forecasters said.
A gradual cooling trend was forecast to occur through early next week, followed by warmer weather late in the week as a ridge of high pressure develops
