While many do not associate tropical storms and hurricanes with the Desert Southwest, it's not unusual to see remnant moisture from these systems pulled into the region several times a year from decaying systems in the Eastern Pacific. This looks to be the case once again, as a trough in the Northwest pulls moisture north from Hurricane Marie this weekend. Thankfully, Marie will remain far offshore, bringing no wind impacts to Southern California, but rain and high surf could cause a few issues.<img src="https://media.weathernationtv.com/app/uploads/2026/09/Screenshot 2026-09-04 073717-1788529053826.png">Moisture will increase this weekend, increasing storm potential this weekend in New Mexico and Arizona. Monsoonal storms could create localized flooding issues yet again in southeastern Arizona. New Mexico will welcome the moisture on dry soils, but hopefully it doesn't become too much of a good thing.<img src="https://media.weathernationtv.com/app/uploads/2026/09/PIC 4-1788566232523.png">Over the weekend, moisture will increase across Southern California, leading to their inclusion in the flood risk. San Diego has a low chance for flash flooding, indicated by the light green color.<img src="https://media.weathernationtv.com/app/uploads/2026/09/PIC 5-1788566243012.png">Marie's moisture will be pulled in this weekend. Saturday night, we'll see the influx of moisture move through Southern California, Nevada and into Utah. Scattered showers and thunderstorms are expected over the weekend, with the afternoons expected to be the most active.<video src="https://media.weathernationtv.com/app/uploads/2026/09/FORECAST-1788566339396.mp4" controls="true" width="100%"></video>Another big impact to watch out for will be high surf and dangerous rip currents. Even without a landfalling tropical storm, waves and rip currents can be greatly impacted. South facing beaches in Southern California should be on high alert for these changing conditions. Expect high surf and dangerous rip currents for the Labor Day Weekend.<img src="https://media.weathernationtv.com/app/uploads/2026/09/Screenshot 2026-09-04 073856-1788529149267.png">If you are going to the beaches, swim near a lifeguard! This is true even for more experienced swimmers.If you ever find yourself caught in a rip current:<ol><li>Don't panic. If you panic and try to swim back to shore against the current, you will exhaust your energy.</li><li>Swim parallel to the coastline. Once you're out of the grip of the rip you'll be able to move towards the shoreline.</li><li>If swimming parallel is too difficult. Float on your back and try to signal for help!</li><li>Listen to the lifeguards and monitor beach conditions before you go into the water.</li></ol><img src="https://media.weathernationtv.com/app/uploads/2026/09/Screenshot 2026-09-02 081848-1788368179615.jpg">Stay tuned to WeatherNation for the latest in the forecast.

Taban Sharifi grew up in Southern California between Los Angeles and San Diego. She is a Certified Broadcast Meteorologist (CBM) with the American Meteorological Society (AMS). She has a B.S. in Atmospheric, Oceanic, and Environmental Sciences with a minor in Environmental Systems and Society from the University of California, Los Angeles (UCLA). Go Bruins! While in school, Taban was a meteorology intern with NBC LA. There she helped forecast daily weather for the greater Los Angeles region and created a playbook to deploy weather sensors for NBC owned-and-operated stations across the country. Her first on-air job took her to San Angelo, Texas, where she was a morning meteorologist and co-anchor. Working in West Texas gave her knowledge and experience covering severe storms. From there, she moved to Palm Springs, California. People think forecasting in California is sunshine all the time, but with temperatures in the 120’s, wildfires, damaging winds, floodings, and earthquakes, the forecasting kept her very busy! She also worked there as a general assignment reporter and told community stories. Taban is excited for the challenge and opportunity to forecast nationally with WeatherNation. She also looks forward to exploring all that Colorado has to offer!

The Pacific hurricane season is showing no signs of slowing down as multiple tropical systems churn across the basin, with warm ocean temperatures and a strengthening El Niño helping create favorable conditions for development. Karina, Lowell, and Marie are all active in the Pacific, though only two of these systems will create impacts for the U.S.Marie isn't expected to get anywhere close to Southern California, but Marie's moisture will get pulled into the Southwest by a trough off the northwest coast. As it digs south, it can tap into the Pacific moisture of Marie and pull it into Southern California, Nevada, and the Four Corners States. We'll be watching the weekend forecast for rain in already soggy, flood-stricken areas.<h1>MORE: <a target="_blank" rel="noopener noreferrer nofollow" href="https://www.weathernationtv.com/news/stormy-cooler-conditions-return-to-the-west">Monsoon Storms Bring Flooding to the Southwest</a><img src="https://media.weathernationtv.com/app/uploads/2026/09/Screenshot 2026-09-02 105610-1788368183778.png">LOWELL</h1>With well above average sea surface temperatures in the Pacific, tropical activity continues to be fast and furious. One storm that will have to be watched for the Hawaiian Islands is Hurricane Lowell. That storm will swing near the western end of Hawaii, bringing impacts to islands like Kaui and O'ahu. While the center of Lowell is expected to pass west of Kaui, its massive wind field will still bring a chance for tropical storm force winds to the islands on Monday. High surf will be another big threat, creating hazards for beach goers and mariners through the whole of Labor Day Weekend. Heavy rain is a possibility as well, though how much rain falls will be determined how closely Lowell gets to the islands. Residents in Kaui, and even O'ahu, should have preparations for wind and rain impacts completed on Sunday.<img src="https://media.weathernationtv.com/app/uploads/2026/09/PIC 4-1788563488935.png"><h1>El Niño Helping Fuel Pacific Activity</h1>The surge in tropical activity comes as El Niño continues to strengthen across the equatorial Pacific. El Niño is characterized by warmer-than-average ocean temperatures across portions of the central and eastern equatorial Pacific. Those unusually warm waters can influence weather patterns around the globe while also creating an environment that can favor tropical cyclone activity in the Pacific.<img src="https://media.weathernationtv.com/app/uploads/2026/09/Screenshot 2026-09-02 105616-1788368212978.png">This year’s El Niño has already strengthened considerably, and forecasts indicate it could become exceptionally strong later this year.While the Pacific remains crowded with tropical systems, many of the current storms are expected to remain over open water. Still, with several additional areas being monitored, the active stretch of the 2026 Pacific hurricane season is far from over.Click here for more on what is happening in the Atlantic Basin: <a target="_blank" rel="noopener noreferrer nofollow" href="https://www.weathernationtv.com/news/Edouard-Impacts-Gulf-Coast">Edouard Impacting the Gulf Coast</a>

Intense rainfall has inundated parts of Texas this week thanks to, what was, Tropical Storm Edouard. Rain totals east of I-45, north of Houston, have come in at over 15 inches for a few areas.<div class="twitter-tweet" style="display: flex; justify-content: center" data-twitt-post-id="2095195048312995975" src="https://x.com/WeatherNation/status/2095195048312995975"></div> The heavy rain led to flash flood emergencies being issued this past Wednesday, as roads became impassable in some areas. High rainfall totals for East Texas due to the heavy rain. <img src="https://media.weathernationtv.com/app/uploads/2026/09/pic4-1788473855278.png"> Additional heavy rain is expected for a few areas on Thursday, leading to a lingering flood threat, primarily due to saturated soils.<img src="https://media.weathernationtv.com/app/uploads/2026/09/pic4-1788474026008.png">The WPC has issued a moderate risk (level 3 out of 4) for parts of eastern Texas, with a level 2 threat that covers portions of the Dallas area. Isolated flooding may linger on Friday before the remnant moisture finally fades.<img src="https://media.weathernationtv.com/app/uploads/2026/09/pic4-1788474917265.png"><h1>Landfall</h1> Tropical Storm Edouard made landfall along the northwestern Gulf Coast on Tuesday, September 1st. The National Hurricane Center used radar data from Lake Charles, LA and Houston, TX to determine maximum sustained winds of 60 mph as it moved ashore around 2:20 PM CT near Johnson Bayou, LA.<img src="https://media.weathernationtv.com/app/uploads/2026/09/Screenshot 2026-09-02 194333-1788399821665.png">Wind speeds across portions of Texas peaked to 90 mph.

During El Nino, temperatures across the Eastern Pacific Ocean become warmer, or above normal. For the hurricane season, this means an increase in tropical activity across the Eastern Pacific.<img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-26 160007-1787781615977.png">These warmer sea surface temperatures also mean an increase in shark activity for Southern California beaches. Meteorologist Taban Sharifi spoke to Dr. Christopher Lowe, professor of marine biology and director of the Shark Lab at California State University, Long Beach on how El Nino brings changes to marine life along the coast.<div data-youtube-video=""><iframe width="640" height="480" allowfullscreen="false" src="https://www.youtube.com/embed/1FcXy4BQcgA" start="0"></iframe></div>As the waters continue to warm through the Fall, Dr. Lowe talked about the changing species that will be seen across the Southern California waters that are not typically there. This includes hammerhead sharks, whale sharks, and even manta rays. This also includes white sharks. The water farther south will get too warm for the white sharks, that are normally off the Baha of California, and they will begin to push north. Dr. Lowe said, "It's going to push those juvenile white sharks that are normally in Mexico into Southern California waters." This is something they have already started to see happen during July and August of this year, and the numbers of these sharks are increasing. Dr. Lowe said the sharks could reach as far north as Santa Cruz, CA.<img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-26 155905-1787784580682.png">There's a sweet spot for water temperatures for these sharks that sits between 64°-72°. Above 82° is when sharks begin to move north. Currently, water temperatures in the Eastern Pacific are significantly warmer than that 82° threshold.A message to beach goers: "Believe it or not, having all those white sharks off that beach might actually keep people safer. Because they are eating sting rays, there are fewer sting rays that might hurt people," said Dr. Lowe.Watch the full interview for more on how close these sharks get to the coastline and how scientists track their behavior.

Expect road closures and possible power outages throughout the day as the rain continues to pour. We also have flash flood watches in effect throughout northern California. Flash flooding might be a possibility near burn scars.

Those burn scars include the Carr-Hirz-Delta fire burn area, the Mendocino Complex burn area, and the Camp Fire burn area.

Take extra time on commutes today, and remember if you see flooding, turn around don't drown. You never know what is beneath the waters. It might be deeper than expected or roads might be damaged.
