Three upcoming storms expected to bring high seas, heavy rain and strong winds this weekend have led the U.S. Coast Guard to issue a caution to local boaters who plan to sail in Bay Area waters.
The succession of tempests will make up "one of the most powerful storms in the past two years," said Steve Anderson, a meteorologist for the National Weather Service.
Approximately 2 to 4 inches of rain are expected to fall in the Bay Area while local mountains could receive up to 8 inches of rain between Thursday and Sunday, Anderson said.
Winds are expected to pick up Wednesday night with gusts reaching 29 mph after midnight and a western swell of 9 to 11 feet with wind waves between 3 and 5 feet through the night, according to the National Weather Service.
The first of the three storms will most likely begin Thursday. With that storm, about an inch of rain is expected to fall, accompanied by 4 to 7 foot wind waves and western swells at 12 to 15 feet and southern swells at 7 to 9 feet, the National Weather Service reported.
Friday morning winds are expected to pick up from 20 mph to 30 mph with gusts as high as 50 mph, Anderson said.
By 10 a.m. Friday rain will most likely pound the Bay Area with about 2 to 3 inches of rainfall, Anderson said.
Combined seas of 14 to 19 feet and winds from 35 mph to 46 mph are expected along with the rain, according to the National Weather Service.
The third storm will be calmer than Friday's and is expected to last through Sunday, bringing about a half inch of rain, Anderson said.
