NOAA has released <a target="_blank" rel="noopener noreferrer nofollow" href="https://www.noaa.gov/news-release/noaa-predicts-below-normal-2026-atlantic-hurricane-season">their predictions for the 2026 Atlantic Hurricane Season</a>. They are calling for a below normal season with 8-14 named storms, 3-6 hurricanes, and 1-3 major hurricanes. For probability, they predict a 35% chance of a near-normal season, a 10% chance of an above-normal season, and a 55% chance of a below-normal season. As a reminder, even below average seasons can have major impacts. All it takes is one storm making landfall for it to be a devastating season in the U.S.NOAA sites several factors in their forecast, including the burgeoning El Ni­­ño, and possible Super Ni­­ño, shaping up in the tropical Pacific. The expectation for an El Ni­­ño event during the peak of the 2026 Atlantic Hurricane season is a big factor in keeping numbers lower than previous years, along with near normal sea surface temperatures, which have been much above average in recent seasons.The confidence in an El Niño developing this summer is quite high, but the remaining question is how strong will the event be? A weak El Ni­­ño typically has a lower impact on the tropics in the Atlantic, while a strong El Ni­­ño has a more consistent impact. Each updated forecast from the Climate Prediction Center shows higher confidence in this year's El Ni­­ño being on the strong side.<img src="https://media.weathernationtv.com/app/uploads/2026/05/Screenshot 2026-05-21 083641-1779374209515.png">Why does El Ni­­ño typically reduce hurricane activity in the Atlantic Basin? The warmer water in the equatorial pacific often leads to a more energetic sub-tropical jet, leading to stronger winds in the upper-atmosphere over the Caribbean. Surface winds in the Caribbean most often comes from the east, known as the trade winds. When these winds lay under strong winds from the opposite (or even the same direction), it leads to strong wind shear which tears hurricanes apart.<img src="https://media.weathernationtv.com/app/uploads/2026/04/Screenshot 2026-04-09 063418-1775740706915.png">“Although El Niño’s impact in the Atlantic Basin can often suppress hurricane development, there is still uncertainty in how each season will unfold,” said NOAA’s National Weather Service Director Ken Graham. “That is why it’s essential to review your hurricane preparedness plan now. It only takes one storm to make for a very bad season.”If this year's name list looks familiar, it's the same one from the historically active 2020 season. There is one difference: the name "Laura" was retired after Hurricane Laura devastated the Louisiana coast. It was replaced with "Leah".<img src="https://media.weathernationtv.com/app/uploads/2026/04/Screenshot 2026-04-09 065301-1775741404492.png"><a target="_blank" rel="noopener noreferrer nofollow" href="https://www.weathernationtv.com/news/csu-releases-first-hurricane-forecast-for-2026">Colorado State University's Tropical Weather Department has already released their early forecast for the Atlantic Hurricane Season.</a> They are calling for a near normal to slightly below average season with 13 named storms, 6 hurricanes, and 2 major hurricanes.

That combination is expected to lead to strong-to-severe storms on Thursday afternoon. The biggest threat will be damaging winds and large hail as storms move through this evening.<img src="https://media.weathernationtv.com/app/uploads/2026/05/Screenshot 2026-03-29 060538-1779370164780.png"><video src="https://media.weathernationtv.com/app/uploads/2026/05/2026-05-21 09-50-43-1779371470664.mp4" controls="true" width="100%"></video><h1>TEXAS</h1>The tail end of the front is dragging into the Lone Star State as well.

A slow-moving frontal boundary that brought numerous days of severe weather to the Plains, has hit a snag down south. This front has stalled out, which will provide the focus for storm chances over the next few days. With multiple rounds of storms on the way, flooding is a growing concern. Some areas of Texas have already seen 3-4 inches of rain!<img src="https://media.weathernationtv.com/app/uploads/2026/05/Screenshot 2026-05-20 043144-1779273210458.png"><h1>FORECAST</h1>Going forward, the heaviest of the rainfall will target the lower Mississippi River Valley, into the Midwest. Some areas will pick up 3-5 more inches with some localized areas surpassing that easily. If you live in a flood-prone area of the southern plains into the Ohio River Valley, be prepared to seek higher ground.<img src="https://media.weathernationtv.com/app/uploads/2026/05/Screenshot 2026-05-20 183732-1779323888225.png">With rounds of heavy rain expected over the next several days, the Weather Prediction Center (WPC) has issued Marginal to Slight chances for Excessive Rainfall into the weekend.<img src="https://media.weathernationtv.com/app/uploads/2026/05/pic5-1779362383380.png"><img src="https://media.weathernationtv.com/app/uploads/2026/05/pic4-1779362505604.png"><img src="https://media.weathernationtv.com/app/uploads/2026/05/pic3-1779362589618.png">You can see that some areas, especially the Texas Gulf Coast, will have multiple days in a row of excessive rain. Flooding is likely with this forecast, and flood emergencies can't be ruled out for travelers. Use caution if you are travelling in these hard-hit areas today.A good reminder to avoid driving through flooded roadways at all costs.

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!

SIMI VALLEY, CA - On Monday, May 18th in Ventura County, California, a new wildfire formed named the Sandy Fire. It has since burned over 2100 acres and grew quickly, threatening life and property. This prompted evacuation orders and warnings to the area.<img src="https://media.weathernationtv.com/app/uploads/2026/05/Screenshot 2026-05-20 175811-1779321590665.png">Footage in the region shows the extent of the smoke and poor air quality.<div class="twitter-tweet" style="display: flex; justify-content: center" data-twitt-post-id="2056736634754809931" src="https://x.com/WeatherNation/status/2056736634754809931"></div>Additional fires have since quickly formed in southern California, despite no red flag warnings or fire weather outlook. The winds managed to be strong enough for fires to quickly get out of control in the areas. The Bain Fire in Riverside started to burn heavy fuels at a moderate rate before quickly burning up to almost 1000 acres. This prompted evacuation orders and warnings for many Riverside Zones.The Bain Fire is burning in Riverside County, CA. This fire began on Tuesday, May 19, and quickly spread to over 1,400 acres. The cause of the fire is still under investigation.<img src="https://media.weathernationtv.com/app/uploads/2026/05/Screenshot 2026-03-29 060538-1779367035809.png">Another fire we are watching is one that possibly started from a shipwrecked sailor off the coast of California.

A big warmup is taking hold across the eastern United States, bringing temperatures that will feel more like midsummer than mid-May. Much of the East Coast, Mid-Atlantic, and Northeast saw temperatures surge into record-breaking territory as a strong area of high pressure settled over the region.&nbsp;Numerous records were broken on Tuesday afternoon, including Newark, NJ, which hit a high of 99 degrees. The NE can see one more day of record warmth before temperatures cool off.<img src="https://media.weathernationtv.com/app/uploads/2026/05/NORTHEAST HIGHS-1779242730674.png">RELATED: <a target="_blank" rel="noopener noreferrer nofollow" href="https://www.weathernationtv.com/news/severe-storms-possible-in-the-plains-midwest-to-end-the-week">Severe Chances on the Plains</a>High temperatures are forecast to climb into the 80s across many areas, while some cities could approach or even reach 90 degrees for the first time this year in the Northeast.

A powerful storm system moving into the western United States will bring winter weather to parts of the Northwest but also to parts of the Southwest.

In particular after fires, mudslides and floods, Southern California now has winter weather advisories that are already posted for high elevation and mountain areas around Los Angeles and San Diego. These advisories will become active on Friday and carry through into Saturday.

3 to 6 inches of snow is expected across some of the highest mountain locations in the region, especially north facing surfaces. Lighter amounts are expected at lower elevations, as low as 2,5oo feet.
