Stormfront pinwheels damaging winds into San Francisco Bay Space; Develops hurricane-like eye
SAN FRANCISCO — A spinning low pressure parked just off the California coast Tuesday morning threatened the Bay Area with 60-mph wind gusts and storm cells with intense downpours and possible thunderstorms.
The system developed a hurricane-like eyewall as it rotated offshore.

Depending on where you live, the showers can be quite intense.
“The accompanying rain appears to be heavy at times, particularly over the Santa Lucia Mountains and Santa Cruz Mountains, where maximum precipitation totals through Wednesday are expected to be 6 to 7 inches and 4 to 5 inches, respectively,” the weather service said.
“The corresponding precipitation totals at lower elevations appear to range from 0.5 to 1.0 inches in the North Bay, 0.75 to 1.25 inches in the heart of the San Francisco Bay Area, and 1.0 to 2.0 inches in the Monterey Bay area.”
The South Bay Weather Service issued a warning for urban and small streams Tuesday morning as heavy rain fell in the area.
While weather conditions during the morning commute made for treacherous driving conditions, the storm’s fury cat-targeted the waterlogged Monterey Peninsula and communities south of Los Angeles. 3 atmospheric flow.
The river will flow as much as 6 inches into the foothills and mountains of the Central Coast and Southern California by Wednesday evening.

“Precipitation rates generally range from 0.25 to 0.50 inches/hour, but local rates of 0.50 to 1.00 inches/hour are possible on the front line and associated with any thunderstorm activity,” the National Weather Service warned.
Due to the very wet conditions and expected rainfall, flood monitoring is in place for the area. The Bay Area, which has just recovered from a violent storm that left 300,000 people without power, once again faced the threat of damaging gusts.
A strong wind warning went into effect at 7am and will linger along the coast for the rest of the day. A strong wind warning was issued for inland communities. The gusts of up to 100 km/h are enough to tear down power lines, tear off branches and topple trees.
“It looks like two bands of particularly strong winds, spreading like the arms of a pinwheel, will quickly pass off the coast of Big Sur,” the weather service said. “First Tuesday morning and second Tuesday afternoon. The highest wind speeds in both instances appear to be concentrated in the southern half of our district, with the highest gusts potentially reaching into the 65 to 75 mph range in the windiest locations.”
Forecasters warned Bay Area residents of the dangers of the winds with the saturated soil and weakened trees present.
“People should avoid being outside in wooded areas and near trees and branches,” meteorologists said. “If possible, stay on the lower floors of your home and avoid windows during the storm.”
Forecasters also warned that with the projected accompanying strong vertical wind shear in the lower troposphere, “one cannot rule out the possibility of a waterspout or local twist over land and must monitor radar carefully.” Small hail could also occur.”
