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>WHAT TO EXPECT</h1><p>Heavy rain has already hit numerous areas in the Southeast this past week, creating major flash flooding issues in Atlanta. A marginal risk for severe weather remains in place for Sunday and into the overnight hours for portions of GA, AL &amp; FL. Damaging winds and hail will be the primary concern. On Monday, we have another chance of strong-to-severe storms, including in Tallahassee and Atlanta. Once again, damaging winds will be the main concern. </p><p><img src="https://media.weathernationtv.com/app/uploads/2026/05/mondayyaa-1779653951757.png">As the low moves through, scattered showers and storms will continue through the holiday on Monday. Heavy rain will also be a concern as this frontal boundary lingers. Always turn around and never attempt to drive through flood waters. </p><video src="https://media.weathernationtv.com/app/uploads/2026/05/ovvv-1779654086424.mp4" controls="true" width="100%"></video><p>Additional heavy rain is expected to increase the potential for flash flooding, in addition to strong storms and severe weather threats.

<p>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.</p><p><img src="https://media.weathernationtv.com/app/uploads/2026/05/Screenshot 2026-05-21 100455-1779379504114.png"></p><p>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.</p><p>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.</p><p><img src="https://media.weathernationtv.com/app/uploads/2026/05/Screenshot 2026-05-21 083641-1779374209515.png"></p><p>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.</p><p><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.”</p><p>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".</p><p><img src="https://media.weathernationtv.com/app/uploads/2026/04/Screenshot 2026-04-09 065301-1775741404492.png"></p><p><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 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.

<p>The National Oceanic and Atmospheric Administration (NOAA) released several important seasonal outlooks today, including their expectations for the upcoming Atlantic Hurricane Season. Hurricane season and summer are expected to be impacted by a burgeoning El Niño, which could be very strong through much of the second half of 2026. <br><br>Among the new outlooks issued are the seasonal forecasts for meteorological summer, which runs from June through August. NOAA is expecting much of the lower 48 to experience above-average temperatures (top of page), with higher confidence across the Western U.S. The Midwest and parts of the middle Mississippi Valley have an even chance for above or below-average temperatures.</p><p><img src="https://media.weathernationtv.com/app/uploads/2026/05/Screenshot 2026-05-21 113803-1779385356524.png"></p><p>Much of the country is forecast to have near-normal rainfall for meteorological summer, but a few areas are favored for below-average precipitation. These include the Texas Gulf Coast, Upper-Midwest, and the Pacific Northwest. In contrast, the Northeastern U.S. is slightly favored to see above-average precipitation. There is some confidence in parts of the Four Corners region having above-average rainfall, indicating the Climate Prediction Center expects an above-average monsoon season.</p><p><img src="https://media.weathernationtv.com/app/uploads/2026/05/Screenshot 2026-05-21 113858-1779385377893.png"></p><p>Not surprisingly, the forecast rainfall in the Four Corners could lead to drought improvement, which is expected in the seasonal drought outlook (above). Drought is also expected to improve in Florida, parts of Texas, and the lower Mississippi Valley. Drought is expected to expand or develop from California through Minnesota.</p><p><img src="https://media.weathernationtv.com/app/uploads/2026/05/Screenshot 2026-05-21 113928-1779385397348.png"></p><p>The North American Monsoon (NAM) develops in Mexico in June and shifts north into the Four Corners, Great Basin, and California into July, August, and September. More data is needed to understand any correlation between El Niño and the NAM, but tropical systems tend to be more active in the Eastern Pacific during El Niño years. Remnants of these systems can greatly increase rainfall during the NAM.</p><p><img src="https://media.weathernationtv.com/app/uploads/2026/05/Screenshot 2026-05-21 114106-1779385397348.png"></p>

<p><strong>SIMI VALLEY, CA -</strong> 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/2026/05/1-1779416671274.png"></p><p></p><p>Footage in the region shows the extent of the smoke and poor air quality.</p><div class="twitter-tweet" style="display: flex; justify-content: center" data-twitt-post-id="2056736634754809931" src="https://x.com/WeatherNation/status/2056736634754809931"></div><p>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.</p><p>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/2026/05/1-1779416718052.png"></p><p></p><p>Another fire we are watching is one that possibly started from a shipwrecked sailor off the coast of California. This is the Santa Rosa Island Fire which is over 16,000 acres. Not many people reside on this island but there are species on the island that are threatened by the fire.</p><p><img src="https://media.weathernationtv.com/app/uploads/2026/05/Screenshot 2026-03-29 061107-1779367133110.png"></p><p>Due to the extent of several wildfires burning in southern California, air quality has worsened in the area, and air quality alerts have been issued for parts of the Greater Los Angeles area.<img src="https://media.weathernationtv.com/app/uploads/2026/05/1-1779416760992.png"></p><p>For more on these, be sure to join us at WeatherNation at :50 past the hour.</p>

How big are hailstones?  That definitely can depend on where you live and how strong an updraft the storm has that produces them!

The best way to find out how large the hail might be that fell in your yard is to take an actual measurement.
