A strong upper-level trough along with monsoonal moisture advecting northward will hone in on southwestern Colorado and northwestern New Mexico over the coming days. Both a flood threat and isolated severe thunderstorms will be possible. <img src="https://media.weathernationtv.com/app/uploads/2025/09/Screenshot 2025-09-10 153101-1757540496125.png"> <img src="https://media.weathernationtv.com/app/uploads/2025/09/Screenshot 2025-09-10 154805-1757540899054.png">A Flood Watch covers much of western Colorado on Thursday, including the San Juan Mountains, where model guidance indicates the higher rain totals. <video src="https://media.weathernationtv.com/app/uploads/2025/09/swcorain-1757540964634.mp4" controls="true" width="100%"></video>The latest model data suggests the heaviest rain will be focused over the same locations for the next few days. Flooding may remain a concern through the rest of the week, with an extension of alerts possible. <img src="https://media.weathernationtv.com/app/uploads/2025/09/Screenshot 2025-09-10 153112-1757540909578.png"><img src="https://media.weathernationtv.com/app/uploads/2025/09/Screenshot 2025-09-10 153419-1757540909575.png">With upper-level support, some thunderstorms may become organized with an increasingly severe threat. Straight-line damaging winds would be the main hazard.<img src="https://media.weathernationtv.com/app/uploads/2025/09/Screenshot 2025-09-10 153425-1757541061279.png">Hints of winter are also in the forecast! Models are indicating that snowfall will occur on the higher elevations of the San Juan Mountains and the Front Range.

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!

<h1>Post Tropical Kiko</h1>Post Tropical Kiko is now a remnant low as it continues to weaken north of Hawaii! During its lifespan, Kiko reached Category 4 status three times. The good news is that the rip current and large swell risk continues to decrease as the storms falls further apart.<img src="https://media.weathernationtv.com/app/uploads/2025/09/1-1757532298396.png"><h1>AREA OF INTEREST</h1>Another potential area of development over the open waters has a high chance of developing in the next seven days, and we could have development by the end of the week.<img src="https://media.weathernationtv.com/app/uploads/2025/09/Screenshot 2025-09-09 163605-1757457374815.png"><img src="https://media.weathernationtv.com/app/uploads/2025/09/1-1757532353656.png">

It's the climatological peak of Atlantic Hurricane Season, so where are the storms?<img src="https://media.weathernationtv.com/app/uploads/2025/09/1-1757531738349.png">The Atlantic Basin remains very quiet for the short term. However, NHC says a tropical wave is expected to roll off of Africa in the next few days and there is a chance for some development in the next seven days. Meanwhile in the next few days, a massive plume of Saharan dust is expected to move into the Atlantic, reducing chances for thunderstorms to organize.<video src="https://media.weathernationtv.com/app/uploads/2025/09/0909-1757452002089.mp4" controls="true" width="100%"></video>The Climate Prediction Center shows several regions in the next few weeks with low to medium confidence of development in the middle of the month, favoring some waves exiting off of the coast of Africa. Given how this season has played out so far with those waves, we'll wait and see.<img src="https://media.weathernationtv.com/app/uploads/2025/09/Screenshot 2025-09-09 150718-1757452042492.png"><img src="https://media.weathernationtv.com/app/uploads/2025/09/Screenshot 2025-09-09 150744-1757452069603.png">Do not let your guard down. September is historically the peak of hurricane season, and ocean conditions remain favorable for additional development. However, the NHC urges residents along the Atlantic basin to monitor updates closely.<img src="https://media.weathernationtv.com/app/uploads/2025/09/Screenshot 2025-09-08 150717-1757365651408.png">As always, preparedness is key. Whether or not this particular system develops into a named storm, it serves as a reminder that the Atlantic remains active and that the window for tropical threats is far from closed. Tune into WeatherNation TV for the latest updates.

From Delaware to Florida, coastal flood alerts have been issued along a large portion of the U.S. East Coast. These are issued for 1-2 feet of inundation, and there are a few factors that are playing a role. A strong high-pressure center over New England and a stationary boundary offshore the southeast coast are going to leave the east coast under persistent onshore winds that are pushing the ocean water onshore.Additionally, beachgoers should use caution due to high rip current risk. These strong, fast-moving currents can pull swimmers away from shore.<img src="https://media.weathernationtv.com/app/uploads/2025/09/Screenshot 2025-09-10 131522-1757532104235.png">With the last full moon, just earlier this week. The high tides are usually enhanced, so this is an additional factor to the widespread coastal alerts.

Rob grew up in South Florida, where daily afternoon storms and hurricanes piqued his interest in meteorology early on. That interest was fostered by his teachers and his father, who one time brought him onto the roof of their home to watch a funnel cloud move through the Everglades several miles away. Years of filmmaking and tv production in high school gradually pushed him toward broadcast meteorology at Florida State University, where he joined and eventually led the student run daily weather show. After graduating with a Bachelors of Science in Meteorology, he began his career at KESQ in Palm Springs, California before heading to KFSN in Fresno and WLOS in Asheville, North Carolina. He has covered a diverse array of extreme weather events, including haboobs and flash flooding in the desert, extreme snow in the Sierra, hurricanes, and Appalachian ice storms. He also enjoys telling stories and reporting about weather issues.

CALIFORNIA - Wildfires in the western U.S. continue to burn, impacting air quality across much of the country. The Garnet Fire, which began in the Sierra National Forest on August 24, 2025, has prompted a <a target="_blank" rel="noopener noreferrer nofollow" href="https://www.fs.usda.gov/r05/sierra/alerts/garnet-fire-closure-order">partial forest closure </a>near the fire.According to the Fresno County Sheriff's Department, some evacuation orders are in effect in the area. The fire has now burned over 56,000+ acres and is approximately 15% contained as of Wednesday AM.<img src="https://media.weathernationtv.com/app/uploads/2025/09/Web 1-1757505269040.png"><img src="https://media.weathernationtv.com/app/uploads/2025/09/1-1757530565722.png">As of Wednesday afternoon, the air quality is still in the unhealthy range from the Garnet Fire. While the Dense Smoke alerts have expired, limit your time outside until the levels continue to drop off! <img src="https://media.weathernationtv.com/app/uploads/2025/09/1-1757530756825.png"><h2>Northwest</h2>Fires burning in the Northwest and in British Columbia, Canada, have worsened air quality across the region and, over the past weekend, even reached the central U.S. If you’ve noticed hazy skies, the smoke from these wildfires is the cause.<img src="https://media.weathernationtv.com/app/uploads/2025/09/Screenshot 2025-09-07 173222-1757287993801.png">When air quality alerts are issued, people with respiratory sensitivities should limit time outdoors. Wearing N95 masks may also be advisable.<img src="https://media.weathernationtv.com/app/uploads/2025/09/1-1757531410859.png">For more on poor air quality and wildfire danger out west, join us on WeatherNation at :50 past the hour for your West regional forecast.
