"As it comes in tonight, expect several hours of light to moderate steady rain, even some embedded downpours, which means there will be some standing water during Thursday's morning commute," said Nicco.

Nicco says "during the afternoon hours, along the coast, we could have some drizzle to some steady light rain, especially in the coastal mountains and even some scattered showers in northern Sonoma, Lake and Mendocino counties."

The North Bay will get soaked around 11 p.m., according to Nicco.

The storm will then quickly move across the South Bay, tapering on Thursday around 5 a.m., explained Nicco. "Leaving us with some leftover showers during the morning commute and some sunshine breaking out in the clouds."

Nicco says his biggest concern on the road will be Thursday's morning commute.

"The earlier you head out, the more likely you are going to run into some standing water," said Nicco.

Make sure you give yourself some extra time and slow down.

"The rainfall amounts are going to be pretty impressive for how short the rain is going to be in its duration, anywhere from a quarter to a half an inch to even double that in the North Bay."
