SAN FRANCISCO (KGO) -- It's a small world, especially when it comes to the atmosphere. The wetter pattern we are about to get in the Bay Area is getting some help from a typhoon thousands of miles away.

Typhoons are the same thing as hurricanes in the United States. They get different names depending on which side of the International Date Line the storm is located.

An Atmospheric River is taking moisture from Typhoon Songda and funneling it towards the West Coast. This is helping to enhance rainfall totals, especially in the Bay Area in the coming days.

The ABC7 weather team is forecasting a moderate storm, which ranks a 2 on the Storm Impact Scale, moving in Thursday night and making a mess of the Friday morning commute. Another storm will arrive Saturday evening. This one will be a lighter storm, a 1 on the Storm Impact Scale. Our wettest spots will see over an inch of rain from these storms combined. However, to our north in Oregon and Washington, some areas could see well over 8" of rainfall.
