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 leading up to the weekend, increasing storm potential on Friday 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/Screenshot 2026-09-04 073744-1788529074333.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/Screenshot 2026-09-04 073823-1788529117119.png">Storms stay concentrated from Eastern Arizona to Colorado Thursday and Friday afternoons before more of Marie's moisture is pulled in. 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/swbams-1788537771844.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.

The unofficial end of summer is bringing another busy travel weekend across the country as Americans head out for Labor Day getaways.&nbsp;Travel is expected to pick up beginning Thursday and remain busy through Monday, Sept. 7, as vacationers take advantage of the long holiday weekend. AAA booking data shows travelers are planning everything from road trips and national park visits to cruises and international vacations.&nbsp;Several major U.S. cities are attracting a large share of holiday travelers. Seattle is leading domestic bookings, with Orlando, Boston, Denver and New York also among the most popular destinations. Seattle’s popularity is being helped by travelers departing on cruises to Alaska.&nbsp;<img src="https://media.weathernationtv.com/app/uploads/2026/09/Screenshot 2026-09-03 072348-1788441841652.png">Road trips will be a major part of the holiday weekend, and travelers should be prepared for periods of heavy traffic. The first significant wave of congestion is expected Thursday afternoon as holiday traffic combines with the normal evening commute. The busiest conditions are expected between 2 p.m. and 7 p.m. Friday could be even more challenging, with heavier traffic possible from around midday through the evening.&nbsp;Saturday afternoon could also bring slower travel, while Sunday is expected to offer some of the better driving conditions of the weekend. Traffic is forecast to increase Monday again as vacationers head home.&nbsp;Some routes could take considerably longer than usual. In Colorado, the trip north from Denver to Fort Collins along Interstate 25 could take roughly 1 hour and 40 minutes around midday Thursday, nearly twice the typical travel time.&nbsp;<img src="https://media.weathernationtv.com/app/uploads/2026/09/Screenshot 2026-09-03 072440-1788441889189.png"> As far as the forecast goes, expected severe weather to continue for the Northeast. Afternoon showers and thunderstorms for the southeast. The Midwest will have the chance for severe weather through the weekend.<video src="https://media.weathernationtv.com/app/uploads/2026/09/2026-09-03 07-26-05-1788442028802.mp4" controls="true" width="100%"></video>It's still all about the heat from the Central U.S. to the Southeast. Here's a look at Saturday's high temperatures.<img src="https://media.weathernationtv.com/app/uploads/2026/09/Screenshot 2026-09-03 073121-1788442314879.png">National parks are another popular option for travelers looking to spend the final stretch of summer outdoors. Denver and Las Vegas are serving as major jumping-off points for visitors traveling to parks across the West, including Rocky Mountain, Arches, Zion and Grand Canyon.&nbsp;<img src="https://media.weathernationtv.com/app/uploads/2026/09/Screenshot 2026-09-03 073709-1788442652697.png">With millions of people expected to be on the move, travelers are encouraged to plan ahead. Leaving early in the day can help drivers avoid some of the worst congestion, while checking road conditions before departure can help identify delays or alternate routes.&nbsp;Drivers should also make sure their vehicles are ready for a longer trip. Batteries, tires, and fluids are among the basics worth checking before hitting the highway. Keeping water, snacks, jumper cables, a flashlight, and first-aid supplies in the vehicle can also help if problems develop along the way.&nbsp;The holiday weekend traditionally marks one of the final major travel periods of the summer season, and whether Americans are heading to the beach, mountains, national parks or another city, crowded roads and airports are likely to be part of the journey.&nbsp;Stay tuned for more of the forecast with WeatherNation TV.

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. <img src="https://media.weathernationtv.com/app/uploads/2026/09/pic4-1788487416333.png">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/Screenshot 2026-09-04 072530-1788528769186.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>

Monsoon Moisture Brings Flooding Across the Four Corners

Screenshot20260901041205png-1788257532510.png

WATCH: Dangerous scenes came out of the Grand Canyon, AZ last week on Friday as flash flooding led to these scenes at Mooney Falls. It is common during monsoon season for flash flooding to happen so rapidly so it is especially important to stay weather-aware when rain is in the forecast.<div class="twitter-tweet" style="display: flex; justify-content: center" data-twitt-post-id="1827752800513671517" src="https://x.com/WeatherNation/status/1827752800513671517"></div>The 2024 U.S. monsoon season typically ends on September 30th, so we are still in the thick of the activity across the desert southwest. High pressure to our east and low pressure to our west have helped to funnel in moisture across New Mexico, Colorado, and eastern Arizona. Areas of New Mexico are picking up on the afternoon rain. Several counties under Flood Watches. Ruidoso in particular has already picked up 0.5" - 0.75" of rain. Recent burn scars, urban areas, and locations where the ground is already saturated from recent rainfall will be especially susceptible to rapid runoff and flash flooding.<img src="https://media.weathernationtv.com/app/uploads/2024/08/Ruidoso-1724790682410.png">Multiple rounds of rainfall and storms could run the risk of seeing over 1-3" of rain in New Mexico by Wednesday night.
