HALF MOON BAY (CBS SF) – Flood waters flowed down Corral Reef Avenue in El Granada after a powerful winter storm front roared across the San Mateo County coast on Thursday morning, quickly spilling more than an inch of rain in a heavy downpour.
The National Weather Service has issued a flood advisory for the area.
“Certain passages at low water can become impracticable”, warned the meteorological service. “Water accumulations in urban areas or other areas are occurring or are imminent.”
“Public and local law enforcement officials have reported ongoing flooding, especially places such as Moss Beach and Millbrae,” forecasters continued.
“Speaking to some of the longtime residents of the coast, they haven’t seen this kind of flooding in this area since 1982,” the district fire protection battalion commander of the coast told KPIX. , David Hibdon.
“It was unexpected, it was raining a lot more than usual,” said Pierre Mugnier, who lives near one of the flooded places.
San Mateo County provided two sandbag stations to help residents prepare for the expected rain throughout the weekend. Firefighters say the ground is oversaturated from all the recent precipitation and cannot absorb much more rain, which contributes to flooding.
“They still have the ‘flooded’ signs but I don’t see as much water as I saw this morning,” said Peg Vaughn, who visited the California Avenue convenience store. a few hours after the flooding of the street in front. “It’s pretty crazy and, as you can see, it’s pretty muddy.”
At one point, authorities guided drivers in single file on Route 1 next to the Half Moon Bay airport.
San Mateo County Parks officials have announced that the entire Camp Sawyer segment of the Crystal Springs Regional Trail is closed due to flooding.
The fire protection district has asked neighbors to make sure their homes are prepared to deal with additional rain and to avoid additional flooding.
“If you live in an area with drains, get together with your neighbors and make sure you keep them clean,” Hibdon said. “Just to be prepared, it’s good to be prepared because you never know what’s going to happen.”
