Rosa continues to lose wind intensity and is now a Tropical Rainstorm near the Baja California peninsula. Rosa’s forward speed will increase over the next 24-36 hours as it interacts with an upper-level low.

Rosa’s deep tropical moisture will move across Arizona, western New Mexico, southern Utah and southwestern Colorado today. This moisture will produce heavy rain across these areas and pose a serious flood threat. Flash flooding and mudslides can be expected across northern Mexico and the Southwest United States, especially across desert areas that typically receive very little rainfall.

Also in the East Pacific, Sergio remains a Hurricane and is centered about 900 miles southwest of the Mexican coastline. Sergio will intensify as it moves westward through a zone of warm water and light wind shear. Sergio will not directly impact any landmasses at this time, but rough surf and rip currents are likely along the Mexican coastlines and southern Baja Peninsula over the next several days. We anticipate Sergio to become a major hurricane later this week.

For Wednesday morning we’ll see remnant Southerly Hurricane energy in the waist to possibly chest high range, (165-175 degrees with 11-12 second intervals), and the winds look pretty for good the AM.

We’ll also see some smallish, SW energy enter the fray from a 215-220 degree angle with 15-16 second intervals.

As a bonus… the West facing breaks should pick up a little NW energy to the tune of waist to chest high from a 300-310 degree angle.

The conditions look pretty good early with light Easterly breezes at 2-5 MPH until noon and 6-9 MPH out of the SW in the afternoon. There’s a 40% chance of rain and the air temp tops out at 70 degrees.

For Thursday morning we’ll see minor, leftover, SW Hurricane energy in the knee to waist high + range.

Also on the table will be that 215-220 degree SW energy…. and also another pulse from the same angle hot on its heels which will fill in later in the afternoon. Nothing real significant but there will be a few fun little sets.

Lastly that NW energy should continue to dish up waist high + sets for the better West facing beaches.

For Friday morning we will see leftover SW swell, leftover NW swell and a very serious chance of some Hurricane Sergio swell starting to show up later in the day. Sergio is projected to roll up the line from a steep 170-175 degree angle and should made his presence felt in the afternoon.

The conditions look okay with variable onshore breezes in the 1-5 MPH until noon and 8-10 MPH winds out of the West in the afternoon. The air temp tops out at 68 degrees on the sand and there’s a 10% chance of rain.

For Saturday morning we will see that Hurricane Sergio swell peak with shoulder to head high + sets for the top South facing breaks. The angle should swing out a bit wider to 175-185 degrees. The best bet will be to find an exposed South facing beach with the OC and San O’ areas being the best bet.

For Sunday morning we’ll see that Hurricane energy hold in the chest to shoulder high zone from 175-185 degrees and in conjunction with that fading Sergio swell we’ll see some fresh NW energy in the chest to shoulder high zone from a fairly steep 300-310 degrees.
