Record high temperatures are once again in trouble this week out west. Another strong area of high pressure is setting up shop and looks to stick around for much of the upcoming week. <img src="https://media.weathernationtv.com/app/uploads/2026/10/Screenshot 2026-10-04 060712-1791115842717.jpg">Temperatures have already shattered daily records but areas like Vista, CA tied an all-time record on Saturday. This dangerous amount of heat will stick around through the middle of the week, when some head advisories and extreme heat warnings will expire. <img src="https://media.weathernationtv.com/app/uploads/2026/10/Screenshot 2026-10-04 061329-1791116050573.jpg">It's not just California that is sweating it out this week. Areas in the Rockies will see temperatures approaching 10-15 degrees above normal this time of year. These will threaten records over the next few days as well. <img src="https://media.weathernationtv.com/app/uploads/2026/10/Screenshot 2026-10-04 061449-1791116096973.jpg">

<h1>Pacific Basin</h1>The Pacific Ocean has been incredibly active so far this hurricane season, with no signs of slowing down.<h2>Rachel</h2>Rachel continues to impact the western Mexico coastline, moving northwest through the weekend. At times, this storm will run into some wind shear and weaken somewhat, but it could strengthen later in the week.<img src="https://media.weathernationtv.com/app/uploads/2026/10/Screenshot 2026-10-04 041858-1791109153334.png"><h1>Atlantic Basin</h1>We now have a new area being monitored in the Gulf waters. It's a low chance for development, but with how inactive it has been in the Atlantic Basin this year, we will be watching this closely. Make sure to check back for more tropical updates if you live along or will be traveling to the Gulf Coast over the next week.<img src="https://media.weathernationtv.com/app/uploads/2026/10/Screenshot 2026-10-04 041934-1791109278759.png"><h1>El Nino Fueling Pacific Activity</h1><img src="https://media.weathernationtv.com/app/uploads/2026/09/Screenshot 2026-09-22 075045-1790085064967.png">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">

Heavy rain continues across parts of Central and South Texas for the rest of the weekend. Moisture continues to pile up along the Gulf Coast from an area of low pressure in the Gulf. Luckily, a cold front is heading south to try to dry things out heading into next week. The best chances of rain and storms will be along the immediate coast.<video src="https://media.weathernationtv.com/app/uploads/2026/10/2026-10-04 04-11-01-1791108693923.mp4" controls="true" width="100%"></video>Through Tuesday, Deep South Texas can see rainfall amounts between 3-6" of rain closer to the coast.<img src="https://media.weathernationtv.com/app/uploads/2026/10/Screenshot 2026-10-04 041145-1791108721890.png">Right on queue, another MODERATE (level 3 out of 4) risk for flash flooding has been issued in Texas again. This time, well to the south, where the heaviest of the rainfall is expected.<img src="https://media.weathernationtv.com/app/uploads/2026/10/Screenshot 2026-10-04 041315-1791108808781.png">Just like for the Southeast, Texas and the rest of the Southern Plains looks very soggy for the long term in the next 7-10 days.<img src="https://media.weathernationtv.com/app/uploads/2026/10/Screenshot 2026-10-04 041343-1791108842343.png">For more on this forecast, tune in :30 past the hour for your full Central Regional.

Deep tropical moisture streaming north from the Gulf is combining with an approaching cold front, setting the stage for widespread showers and thunderstorms from the Gulf Coast into the Southeast. Excessive rainfall will be likely over the next few days. Here is the outlook for Sunday.<img src="https://media.weathernationtv.com/app/uploads/2026/10/Screenshot 2026-10-04 040556-1791108370174.png">Sunday’s greatest flooding concern will focus along portions of the central Gulf Coast, including areas from Louisiana east toward the Florida Panhandle.&nbsp;A tropical wave moving through the Gulf is transporting an unusually moisture-rich air mass toward the coast. Atmospheric moisture levels are expected to reach near-record or record territory for early October in some locations.&nbsp;<img src="https://media.weathernationtv.com/app/uploads/2026/10/PIC 5-1791058490540.png"><h1>Timing</h1>After all the heavy rain throughout the Southeast on Saturday, more heavy rain is on the way for the rest of the weekend. Here is a look at the latest timing for all the showers and storms. Flooding will continue to be a big weather risk through early next week for these areas.<video src="https://media.weathernationtv.com/app/uploads/2026/10/2026-10-04 04-06-50-1791108435090.mp4" controls="true" width="100%"></video>Rainfall totals of 3 to 6+ inches are possible Saturday near parts of the Gulf Coast, with locally higher amounts. While some locations entered the weekend with relatively dry ground, rainfall of that magnitude could still overwhelm drainage systems and produce pockets of flash flooding, especially in urban and low-lying areas.&nbsp;<img src="https://media.weathernationtv.com/app/uploads/2026/10/Screenshot 2026-10-04 040725-1791108464091.png">The pattern should begin shifting south by Monday as the front continues moving through the region toward Florida, but flooding concerns will not immediately disappear.&nbsp;Additional heavy rain will continue to be the focus across southeastern Georgia and northern Florida, including areas around Jacksonville. With some locations already receiving significant rainfall over the weekend, additional downpours could cause isolated flooding.&nbsp;<img src="https://media.weathernationtv.com/app/uploads/2026/10/Screenshot 2026-10-04 040937-1791108594708.png">The long term forecast keeps the Gulf Coast very soggy into the middle of October. At least the temperatures are cooling off behind these fronts heading into the month of October.<img src="https://media.weathernationtv.com/app/uploads/2026/10/Screenshot 2026-10-03 070128-1791032535237.png">Stay tuned to WeatherNation TV for additional details.

<h2></h2><div class="twitter-tweet" style="display: flex; justify-content: center" data-twitt-post-id="2105658995948281901" src="https://x.com/WeatherNation/status/2105658995948281901"></div><h2>WHAT TO EXPECT</h2>Tropical moisture from the remnants of Polo and the Gulf have surged north and met a frontal boundary. 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!

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!

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.

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.

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.

The same volcano that has erupted 3 previous times this year has started up again. Near Grindavik, the volcano started erupting late Saturday night. The Icelandic Met Office said a 2.9 km (1.8 mile) fissure formed between Mount Hagafell and Mount Stora Skogfell.<img src="https://media.weathernationtv.com/app/uploads/2024/03/iceland activity-1710767060008.png">The Met Office mentioned that the activity has waned noticeably over the past 24 hours but at times the lava was reaching speeds of one kilometer per hour (that's a little over half a mile per hour). While the pace of the lava has slowed considerably, if it makes it to the sea and rapidly cools, it could lead to some potentially hazardous gases. The Icelandic Met Office does not believe this is a likely outcome unless something changes.<video src="https://media.weathernationtv.com/app/uploads/2024/03/VO_031624_INTL_GRINDAVIK, ICELAND_OH HEY THAT VOLCANO IN ICELAND IS ERUPTING AGAIN_YOUTUBE_RUV_NC_E031624-1710761313444.mp4" controls="true" width="100%"></video>A state of emergency was declared for the southern portion of the peninsula on Saturday, with "hundreds" evacuated from the Blue Lagoon thermal spa.<video src="https://media.weathernationtv.com/app/uploads/2024/03/VON_031624_INTL_REYKJANES PENINSULA, ICELAND_STATE OF EMERGENCY ISSUED AS VOLCANO ERUPTS FOR THE 4TH TIME IN 3 MONTHS_SF_PUBLIC SAFETY DEPT OF THE NATIONAL POLICE_NC_E031724-1710761286552.mp4" controls="true" width="100%"></video>
