across the bay area. we'll get that out of the way first. let's take you to the forecast. the main reason why we're getting all of this anticipated rainfall is that atmospheric river or pineapple express, you probably heard both those terms srgs poised to hear us from the north bay toward the south bay. in advance of this, we do have a flash flood watch that has been issued for saturday night at 6:00 p.m. until sunday at 9:00 p.m. that's the zone when we could have the heaviest rainfall. we may have some fast moving waters. stay with us as we'll have full coverage throughout both days. a look at the time line. you can see we have the rainfall developing just offshore at 9:00 p.m. we likely won't see more rain until saturday morning and it could be heavy at times. the temperatures won't be as cold as this tropical air has some warm weather associated with it. 50 in the south bay. you'll need umbrella and please take it slow. 51 for the east bay and 41 expected for the north bay. let's bring it back to the futurecast and we'll push this through weekend. we have the rainfall for saturday morning, as you've been mentioning. we may undergo a little break by 6:00 p.m. on saturday. don't let your guard down. once we hit saturday night, right around 11:00, that's when that atmospheric river, the pineapple express, is poised to point right toward the bay area. all of our heavy rainfall depends on that happening. every single forecast model shows it. from saturday at 11:30, with heavy rainfall continuing into 9:00 a.m. on sunday and likely areas of heavier rain into 5:00 p.m. on sunday. so wet all weekend long but sunday is the heaviest. what about rainfall totals? haven't seen a big change on it. i know there's a lot of colors here. you can look at the keys on the top. for the north bay, a lot of red and purple. same thing for the peninsula in east bay. good for two to four inches. and san jose, two to three inches. but check this out. the zone of white, we could have six to eight inches possible for the higher elevations. thought water will mean the increased flooding threat. guerneville river could reach flood stage sunday night. we're following napa river. that's near flood stage. the gaud ho, the guadalupe rive. sunday on, and off rainfall. temperature in the 50s for san francisco. interior valleys also remains cool. we may not be out of this river flooding threat until thursday or friday of next week. sunday is the worst. >> to see that map with the red and the purple. >> and that thing is waivering. >> thank you. up next, a miserable
