Isaias ended the late-season streak of no hurricanes in the Atlantic, but how will the rest of the season shape up? Record-breaking wind shear is likely to continue to limit most tropical systems in the Atlantic, but a few more storms are still possible.<h1>Atlantic Basin</h1>We now have a new area being monitored for tropical development over the next week. Our coastal low could take on some subtropical characteristics. Regardless of development, this low will bring rain, wind, and coastal impacts to the Atlantic Coastline.<img src="https://media.weathernationtv.com/app/uploads/2026/10/pic6-1792259669418.png"><h1>Pacific Basin</h1>The Pacific Ocean has been incredibly active so far this hurricane season and looks to continue to create additional activity through the next week. Several systems could bring impacts to the United States. Trudy is running into less favorable conditions for tropical intensification. This storm became a major hurricane on Friday, but it has since weakened and is now expected to be near category 1 status as it brushes the coast of Jalisco, Mexico.<img src="https://media.weathernationtv.com/app/uploads/2026/10/PIC 5-1792192411993.png">Another system is expected to form in the wake of Trudy, with the NHC giving the potential a high chance in the next week. This system looks to move WNW initially, but could curve back east in the long term.<img src="https://media.weathernationtv.com/app/uploads/2026/10/Screenshot 2026-10-17 073419-1792244077541.png"><h1>Western Pacific / Guam</h1>Super Typhoon Champi is bearing down on Guam as a category 4 storm. Thankfully, the core is compact and will hopefully miss a direct hit on the island, but it will be a close call and residents should be prepared for major hurricane impacts.<video src="https://media.weathernationtv.com/app/uploads/2026/10/2026-10-17 07-14-03-1792242917871.mp4" controls="true" width="100%"></video>After Champi moves through the Marianna Islands and Guam early Sunday, the storm is expected to head WNW toward Taiwan.<img src="https://media.weathernationtv.com/app/uploads/2026/10/Screenshot 2026-10-17 071430-1792242909538.png"><h1>El Nino Fueling Pacific Activity</h1><img src="https://media.weathernationtv.com/app/uploads/2026/10/Screenshot 2026-10-16 111954-1792171201698.png">The Eastern Pacific has set a new record for the most energetic season since record keeping began. The ACE has surpassed 318, which was the previous record set in 2018.The surge in tropical activity comes as El Nino continues to strengthen across the equatorial Pacific. El Nino 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 2026-09-28 194202-1790646127358.png">This year’s El Nino has already strengthened considerably, and forecasts indicate it could become exceptionally strong later this year.<img src="https://media.weathernationtv.com/app/uploads/2026/09/Screenshot 2026-09-12 063433-1789216512410.png">

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.

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!

A major temperature divide is unfolding across the United States as millions experience a true taste of fall while parts of the West continue to deal with summer-like heat.&nbsp;A surge of cooler air has spread across much of the central and eastern United States, sending temperatures tumbling and bringing some of the chilliest conditions of the season so far. Meanwhile, unusually hot weather continues across portions of the West Coast, where temperatures are running well above what is typical for early October.&nbsp;Summer Hangs On in the West&nbsp;While jackets are coming out farther east, residents across portions of the West are still dealing with significant heat.&nbsp;Temperatures across parts of California and the interior West are running roughly 10 to 15 degrees above average in some locations. Triple-digit temperatures have even been recorded in portions of Southern California despite the calendar moving deeper into October.&nbsp;Los Angeles experienced consecutive October days with temperatures reaching at least 100 degrees, highlighting the intensity of the unusual fall heat.&nbsp;The persistent warmth stretches beyond Southern California, with above-average temperatures extending through portions of the Great Basin and toward the northern Rockies.&nbsp;Over the next 3 days, many cities will be near, tie, or break the current records.<img src="https://media.weathernationtv.com/app/uploads/2026/10/Screenshot 2026-10-07 035357-1791366853404.png">Heat alerts remain in place through Friday.

Temperatures are dropping into the 30s and 40s across parts of the northern tier, Great Lakes and Northeast, creating the potential for frost in some of the coldest locations.&nbsp;For areas that have enjoyed a relatively warm start to fall, the change may feel especially dramatic.&nbsp;The arrival of the cooler air is also pushing temperatures below seasonal averages across portions of the central and eastern U.S., signaling a more traditional October weather pattern.&nbsp;<img src="https://media.weathernationtv.com/app/uploads/2026/10/Screenshot 2026-10-07 040003-1791367220514.png">A Coast-to-Coast Temperature Contrast&nbsp;The dramatically different conditions are creating a weather map that looks more like two different seasons.&nbsp;Much of the East is experiencing crisp mornings, cooler afternoons, and increasing frost potential, while parts of the West remain firmly locked in a pattern more typical of late summer.&nbsp;<img src="https://media.weathernationtv.com/app/uploads/2026/10/Screenshot 2026-10-07 040204-1791367341750.png">Eventually, the western heat is expected to ease as the weather pattern shifts.

This has equaled a formula of very heavy rainfall. Flood alerts are in place through Thursday across portions of the plains and Midwest. The soils for this part of the country are already very saturated for many. This means adding more rainfall can lead to flooding of rivers, creeks, and streams, and flash flooding is not out of the question.<img src="https://media.weathernationtv.com/app/uploads/2026/10/PIC 4-1790897782083.png"><h2>TIMING</h2>Rounds of heavy rain will continue on and off. Isolated areas of flooding will be possible. Friday, this low will move east, and we will see drier conditions by the end of the week.<video src="https://media.weathernationtv.com/app/uploads/2026/10/FORECAST-1790897919777.mp4" controls="true" width="100%"></video><h2>TOTALS</h2>Folks can expect very heavy rainfall, with most seeing around 2"- 4". Some localized areas of a half foot will be possible! Never try to drive through floodwaters, and make sure to take any flood alerts and warnings seriously. If you live in an area prone to flooding, make sure to have an action plan in place if flooding develops! <img src="https://media.weathernationtv.com/app/uploads/2026/10/PIC 5-1790897796211.png"> Make sure to tune into WeatherNation for the latest forecast!

Plains & Midwest: Slow Moving Storms Increase Flood Threat

In the last month, the southwestern states of New Mexico and Arizona have seen their fair share of monsoon showers and storms.<div class="twitter-tweet" style="display: flex; justify-content: center" data-twitt-post-id="2103622200872079365" src="https://x.com/WeatherNation/status/2103622200872079365"></div>This week, tropical moisture is pushing across the Southwest and plains. This tropical moisture, from Hurricane Polo, will bring the potential for significant flooding across the region.<img src="https://media.weathernationtv.com/app/uploads/2026/09/poloooo-1790728785495.png">The flooding has already been seen across the Southwest, including Nevada.<div class="twitter-tweet" style="display: flex; justify-content: center" data-twitt-post-id="2104753032432910655" src="https://x.com/WeatherNation/status/2104753032432910655"></div>A major push of this moisture will continue to move through.. Several more inches on top of what has already come down are expected. This can quickly lead to flash flooding and debris flows, especially over burn scars. The heaviest of the activity, now expected in Colorado and the Central Plains.<img src="https://media.weathernationtv.com/app/uploads/2026/09/Screenshot 2026-09-30 054240-1790768613194.png">The Weather Prediction Center (WPC) has a moderate (level 3 out of 4) flooding threat in place for portions of Colorado and New Mexico. The flooding threat will taper off by late-week.<img src="https://media.weathernationtv.com/app/uploads/2026/09/overnighssss-1790820790763.png">Make sure to tune into Weathernation for the latest updates on the forecast.

Another Round of Flooding Possible for the Southwest

Hurricane Nolo spared the Hawaiian Islands from another direct impact this season, instead stalling about 150 miles south of the Big Island before heading west. Heavy rain and wind still impacted the islands, and will continue through the middle of the week as Nolo swings past Kauai. Field correspondent Jonathan Petramala was on the Big Island to bring us those impacts over the weekend.<video src="https://media.weathernationtv.com/app/uploads/2026/09/LL_TRT 1.14_JP GIVES UPDATE ON NOLO_MS_E092626-1790520644996.mp4" controls="true" width="100%"></video><h1>Forecast / Impacts</h1>Nolo's impacts, including flooding, are not done with yet for the Hawaiian Islands. As Nolo heads north through the midweek, heavy rain on it's eastern side will hit the western Hawaiian Islands. 3-5 inches of rain could fall on Kauai, bringing flooding to the region. Kauai sustained a lot of damage just a few weeks back as Hurricane Lowell passed the island barely to the west.<img src="https://media.weathernationtv.com/app/uploads/2026/09/Screenshot 2026-09-28 074803-1790603893032.png">Nolo looks to stall for a day as it then slowly heads farther west, keeping some rain and wind impacts around through at least Thursday. <img src="https://media.weathernationtv.com/app/uploads/2026/09/Screenshot 2026-09-28 074651-1790603234688.png"><video src="https://media.weathernationtv.com/app/uploads/2026/09/forecassssssss-1790557751613.mp4" controls="true" width="100%"></video><h2>Wind / Waves</h2>As Nolo tracks west, wave heights will still be on the high side, bringing hazards to boaters and beach goers. Southward-facing beaches can see increased swell and surf over the next few days.<img src="https://media.weathernationtv.com/app/uploads/2026/09/Screenshot 2026-09-28 075119-1790603514846.png">Stay with us on WeatherNation for the latest updates.
