00:00Welcome back to AccuWeather Ahead.

00:02Overall, we're going to be tracking more heavy rainfall

00:04continuing in the forecast here across the southwest

00:07and southern parts of California.

00:09The overall timeline is going to be Wednesday night,

00:12so throughout the afternoon on Wednesday, we're going to stay dry.

00:15But late Wednesday, we're going to see these showers pushing in from south to north,

00:20so the farther south you are, the earlier your rainfall is going to begin on Wednesday.

00:25So Wednesday evening, Wednesday night is when the rain starts to move in.

00:28It's going to persist throughout the day on Thursday,

00:31and then the rain will slowly start to taper off on Friday morning.

00:35This is leftover tropical moisture from what was Hurricane Mario.

00:39So how much rainfall are we expected to see?

00:41Well, take a look at this.

00:42Widespread, one-inch totals, even some one- to two-inch totals there

00:46in the mountains across southern parts of California.

00:49So Los Angeles, San Diego, up to an inch of total rainfall will be possible,

00:53but we can't rule out the possibility of more rainfall there for the Los Angeles metro,

00:57especially the record to beat for a September afternoon for total rainfall in one day

01:02is a little bit over three inches.

01:04That was set back in the 1930s, so a very old rainfall record.

01:08We'll see if we can challenge that here as we head throughout your Wednesday after,

01:11or your Thursday, I should say.

01:13Wednesday, you can see the rainfall slowly starting to work its way into the forecast.

01:17Overall, it's going to stay warm, so no real concerns there.

01:20Wednesday across the rest of the region, you can see,

01:22look at the temperatures before the rain moves in.

01:24We'll be in the low 90s there for Los Angeles and triple digits for both Fresno and Bakersfield.

01:3083 in San Diego, still plenty warm for this time of year.

01:33But on Thursday, here comes that rainfall.

01:35Once again, primarily the heaviest rainfall totals in the mountains there across the southern California

01:40with the heaviest rain across southern parts of Arizona as we end on Thursday afternoon.

01:45Stay right here with AccuWeather Ahead.

01:46We'll be right back right after this.
