A slow-moving storm will usher rain across California through the end of the week, and for some areas, it will be the heaviest rain since Hurricane Hilary.

00:00 You know, we always say it never rains in Southern California.
00:04 It pours, you know, like the song.
00:06 But it's not just Southern California, but really the whole Golden State we're watching
00:09 for right now.
00:10 Let me show you.
00:11 We'll start with San Francisco, where you'll notice that in a given December, at least
00:15 to this point, December 20th, we should see about two and a half inches of rain.
00:20 We've had just about half of that, given an inch and a quarter or so in the month of December.
00:25 And honestly, most of that has been the past 48 hours in San Francisco.
00:29 You'll notice San Francisco a couple days ago looked more like San Diego.
00:32 A big fat goose egg here on the board.
00:35 Zero rainfall into San Diego so far in September or December, I should say, where we've generally
00:41 seen about an inch to this point.
00:43 But we're about to give even more rain back to the Golden State here.
00:47 And it's a problem-solution kind of situation.
00:49 Let's just talk about this first.
00:51 San Diego, LA, San Francisco, Sacramento, there's rain in your active weather exclusive
00:54 forecast as our storm comes in to the California coast here.
00:58 Now, first of all, that rain has started in Northern California, which is why we've seen
01:03 an increased amount of rainfall in San Francisco, for example, into the Bay Area, even in Sacramento
01:07 as well.
01:08 But that has led to a lot of flooding in the Sacramento Valley and even as you're getting
01:12 into the Bay Area itself.
01:14 Now the thing is, this rain is going to start drifting through today further south along
01:18 I-5 and then along the coast.
01:19 Ready?
01:20 Watch for your rainfall.
01:21 Just going to let it play out for a second.
01:23 Yeah, you see that little area of yellow?
01:25 This is right as you're getting into Santa Barbara, Ventura, and even heading down toward
01:28 LA and San Diego, we are looking at increased rainfall today, tomorrow, and Friday.
01:34 Increased rainfall to the point that flooding is once again a concern.
01:37 Not just flooding, but also the potential for mudslides and flooding in burn scar areas.
01:43 What does that mean?
01:44 Well, remember, burn scars are essentially what happen after a fire.
01:47 It looks like a scar if you were to look at the ground from the air.
01:50 It looks like a scar on your skin, but on the earth.
01:52 Now, those burn scars, they don't accept the water.
01:55 The soil does not accept the water right away.
01:57 Just like dried out ground with a drought, for example.
02:00 It's like a cementing effect.
02:01 So what happens?
02:02 Well, the water runs over the ground and you get even more flooding and sometimes mudslides
02:06 too.
02:07 I want to mention it's not even just for California we're concerned here, but as you're getting
02:10 through the California desert and out into southern Arizona, cities like Tucson and Phoenix,
02:15 we don't have a blockbuster amount of rain by, let's say, I don't know, Jacksonville,
02:19 Florida standards, but even half an inch is enough in these places to cause some problems
02:23 with flooding.
02:24 Now, in terms of the numbers, let me show you what we've got here.
02:27 Half an inch, that's small for this storm.
02:29 You can see, for example, Fresno looking at half an inch to an inch, but Santa Barbara,
02:33 the epicenter here over the next few days, looking at three to six inches of rain.
02:38 Even as we head to LA, two to four inches of rain.
02:41 And just a reminder for you, LA generally sees about two and a half inches in the entire
02:46 month of December.
02:48 So we could see about a month's worth of rainfall, not just into LA, but into many of our California
02:52 cities.
02:53 Make sure you're staying weather aware as we head through the rest of the week.
02:56 Thanks for watching.
02:57 Have a great day.
