The Pacific Ocean has been incredibly active so far this hurricane season, and it shows no sign of slowing down. Meanwhile, the Atlantic remains mostly quiet, as record wind shear continues to tear apart tropical waves moving off Africa. There is a high chance of tropical development being monitored in the Atlantic Basin.<h1>Atlantic Basin</h1><img src="https://media.weathernationtv.com/app/uploads/2026/09/pic4-1789755696270.png">There is an area being monitored east of Bermuda with a medium chance of tropical development. Right now, no deterministic models love this area, but plenty of AI models seem to. Worth watching, but again, not threatening unless you're going to Bermuda.<img src="https://media.weathernationtv.com/app/uploads/2026/09/pic3-1789755848030.png">The end of September and start of October could get interesting in the Atlantic, as more widespread lift is expected to develop. Wind shear is still at a record high, which should be able o crush any waves coming off of Africa. Tropical development will have better potential in the western Atlantic and Gulf, where shear is much lower.<img src="https://media.weathernationtv.com/app/uploads/2026/09/Screenshot 2026-09-17 091009-1789657855421.png"><h1>Eastern &amp; Central Pacific Basins</h1>Several systems are being monitored in the Pacific, with good chances for two of the waves to develop into tropical cyclones. The central wave will track west, while the more easterly wave could stay closer to Mexico.<img src="https://media.weathernationtv.com/app/uploads/2026/09/WEB 1-1789739418564.png">Neither has a clear path toward land yet, but both are worth monitoring for interests in Mexico and Hawaii. Global models develop both systems, with the central wave looking at better conditions to strengthen quickly as we move into next week. Here is a snapshot<img src="https://media.weathernationtv.com/app/uploads/2026/09/WEB 5-1789739526003.png"> of the model by Wednesday.<h1>El Niño Fueling Pacific Activity</h1><img src="https://media.weathernationtv.com/app/uploads/2026/09/Screenshot 2026-09-15 105410-1789491264736.png">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 2026-09-16 073748-1789565873978.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">

A ridge of high pressure that's controlled the weather pattern in the U.S. for much of the past month is still calling the shots for the next few days. While folks under the ridge have been dealing with record heat, storms tracking around the ridge in the north have continued to pummel the Midwest and East Coast with heavy rain and gusty winds.<div class="twitter-tweet" style="display: flex; justify-content: center" data-twitt-post-id="2100200528651198923" src="https://x.com/WeatherNation/status/2100200528651198923"></div>The same storm track through the Midwest will persist into early Sunday, with several rounds of heavy rain anticipated. This will increase the flood threat before a drier pattern develops next week.<img src="https://media.weathernationtv.com/app/uploads/2026/09/1-1789696996361.png">The heaviest of the rain moving forward through the weekend positions itself across Iowa, Wisconsin, and Illinois (top of page), with elevated flood risks from the WPC through Sunday (below). The risk gets very dangerous by Saturday with a Moderate Risk for areas of Illinois and Wisconsin.<video src="https://media.weathernationtv.com/app/uploads/2026/09/FORECAST-1789773268692.mp4" controls="true" width="100%"></video><h1>Severe Storms &amp; Timing</h1>Severe storms will be possible in the warm sector of the passing fronts, with strong winds, hail, and isolated tornadoes possible.

No surprise here: More records were broken across the Southern U.S. on Wednesday (above). Dallas, TX has had a very hot September. Dallas, TX did not break a record high today, but they did record another high temperature of 100 degrees. This is the most days at or above 100° the Dallas metro has ever seen now at 15 days. And this year Dallas is climbing in most 100° days, and now we have our 3rd-longest stretch of dry weather too. <img src="https://media.weathernationtv.com/app/uploads/2026/09/WEB 6-1789739697717.png">The Heat paired with very dry conditions, is now leading to brush &amp; wildfire issues for the South Central Plains<div class="twitter-tweet" style="display: flex; justify-content: center" data-twitt-post-id="2100336425468387653" src="https://x.com/WeatherNation/status/2100336425468387653"></div>Heat Advisories remain in place through this week.

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!

Monday proved to be an active severe weather day for the plains. The significant wind threat definitely materialized across this region, giving us wind reports out of Nebraska, close to 90 mph!<img src="https://media.weathernationtv.com/app/uploads/2026/09/Screenshot 2026-09-15 034852-1789466001637.png">Tuesday, another marginal threat for severe weather stretches all the way from Texas to Southern Michigan. Cities in the risk include Kansas City, Chicago, and Indianapolis. Damaging winds will be the main concern on Tuesday.<img src="https://media.weathernationtv.com/app/uploads/2026/09/Screenshot 2026-09-15 034906-1789466030835.png">These storms are expected to form and roll on through around dinnertime.

<h1>WHAT TO EXPECT </h1>Record rainfall has fallen across the Northeast. Bridgeport, CT, saw a daily rainfall record of 4.25" on Sunday! Multiple cities saw rainfall totals of 3-4 inches these past few days. Overnight, a few storms will be possible as the cold front moves through, but things will continue to taper off into the overnight hours. <h1><img src="https://media.weathernationtv.com/app/uploads/2026/09/Screenshot 2026-09-13 072247-1789305785489.png">GENERAL THUNDERSTORMS</h1>As a cold front works through, there is a general risk for thunderstorms overnight. This was downgraded by the SPC, as earlier on Sunday there was a severe threat. Now overnight, you can see a few storms and isolated heavy downpours. <img src="https://media.weathernationtv.com/app/uploads/2026/09/ne overngith-1789348423494.png"><h1>OVERNIGHT </h1>As the frontal boundary moves through, there will be a few storms developing along it.

Storms Winding Down Across Northeast

Temperatures not only broke records on Wednesday but the heat index for some Southern California cities hit near 120° (above). 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. The leftover moisture from Marie that streamed into the area over the holiday weekend is still lingering. Rainfall totals from Marie brought 2" in some locations. This also significantly increased the high surf and rip currents over the weekend holiday. Beach erosion and coastal impacts have been significant! <div class="twitter-tweet" style="display: flex; justify-content: center" data-twitt-post-id="2097052283859070982" src="https://x.com/WeatherNation/status/2097052283859070982"></div>The higher moisture is also impacting the heat across the region. Dew point temperatures have been in the 60s and 70s. Heat Alerts remain active through Thursday.<img src="https://media.weathernationtv.com/app/uploads/2026/09/Screenshot 2026-09-09 190346-1789002230793.png">Temperatures across this area are running 10-20° above average for Thursday, before more seasonable temperatures for Friday. Near 90 is expected for San Diego! When the humidity is factored in, temperatures could feel nearly 10 degrees warmer, and today that humidity is lingering. <img src="https://media.weathernationtv.com/app/uploads/2026/09/Screenshot 2026-09-09 190400-1789002244390.png">Below are just a few of the records that broke in Southern California on Wednesday. Temperatures will start to reach near normal again for many by the weekend.<img src="https://media.weathernationtv.com/app/uploads/2026/09/Screenshot 2026-09-09 190417-1789002291052.png">Had plans to hit the beach and beat the heat? Might not be the best idea to head into the water. Beach hazards statements have been issued for coastal California. Mainly, large waves and dangerous rip currents will be the threats to watch out for. Some of these alerts will last through the rest of the work week.<img src="https://media.weathernationtv.com/app/uploads/2026/09/Screenshot 2026-09-09 190510-1789002316119.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.

<h1>Looking Back</h1>
Checking back on VIPIR Radar from early this morning you can see all the rotation from this storm.  Checking the velocity from the radar site north of Nashville after midnight, the rotation is very strong and clear. The velocity shows the inbound and outbound winds in relation to the radar.  Just looking at these maps you can clearly see a tornado with strong rotation.
