A typhoon enhanced storm set to sweep through the Bay Area and slam the region with rain and heavy wind is still on track to hit Friday morning, forecasters said.

The storm, which will bring moisture associated with Typhoon Songda that wreaked havoc in the western Pacific days ago, will bring heavy rains just in time for the morning commute on Friday morning, said Roger Gass, a meteorologist with the National Weather Service in Monterey. By the late afternoon Friday, the weather will mostly consist of rain showers.

Heavy winds of up to 30 mph with gusts up to 40 are also expected with Friday’s storm, which will bring the most rain to the region since March.

By the end of the weekend, San Francisco could see more than an inch of precipitation while the North Bay Mountains could see up to four, Gas said.

The National Weather Service has also issued a coastal flood advisory and a high surf advisory for the Bay Area starting at 3 a.m. Friday and running to 9 p.m.
