Each year, Colorado State University's Tropical Meteorology Project releases multiple forecasts for the Atlantic Hurricane Season, including one of the earliest issued among major forecasters. On August 5, Dr. Phil Klotzbach and his team released their final update heading into the peak of the season. With El Niño holding strong, it's not surprising that CSU continued their below average forecast for the season. They expect 9 named storms, 4 hurricanes, and 1 major hurricane.<img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-05 075704-1785938232754.png"> This forecast includes Tropical Storm Arthur, which made landfall along the Texas coast in mid-June and brought tornadoes and flooding rain to Louisiana and Mississippi, and Tropical Storm Bertha, which traced the Gulf coast in July with minimal impacts. Remember, as Arthur proved, even below average seasons can have major impacts.NOAA is expected to release an update to <a target="_blank" rel="noopener noreferrer nofollow" href="https://www.weathernationtv.com/news/noaa-predictions-for-the-2026-hurricane-season">their seasonal forecast </a>this week. We'll bring you those numbers as soon as they become available. <h1>FORECAST FACTORS</h1>You've probably heard rumblings about the strengthening El Ni­­ño, and possible Super Ni­­ño, shaping up in the tropical Pacific. The continuation of El Ni­­ño during the peak of the 2026 Atlantic Hurricane season is a big factor in CSU's below average forecast. Near to slightly above normal sea surface temperatures will also play a role, considering they have been well above average in recent seasons.<img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-05 080509-1785938944958.png">Why do El Ni­­ños 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">We are now heading into the peak of the Atlantic Hurricane Season. Starting in August and lasting through October, we climatologically see the bulk of our tropical system development. <img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-05 080540-1785939101444.png"><img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-05 080526-1785939101442.png">Even with a slightly below average season, two major hurricanes are expected with many other named storms. Any named storm that hits land can have major to extreme impacts, so stay prepared and stay tuned. WeatherNation will always keep you updated on the latest in the tropics!

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!

SPOKANE, WA - On Saturday, August 1st, the Old Trails Fire ignited northwest of Spokane. This fire was fueled by hot, dry conditions and wind gusts up to 45 mph, which helped the fire spread rapidly through grass and brush before reaching neighborhoods. The fire eventually crossed the Spokane River, creating additional challenges for firefighters.UPDATE: The cause still remains under investigation, but a convicted felon has been arrested on an arson charge as the primary suspect for starting the Old Trails Fire, which has now burned over 3600 acres.<h3>Impacts:</h3><ul><li>The Spokane Complex, consisting of the Old Trails, Autumn Lane, and Fairview fires, has scorched over 10,000 acres with 0% containment</li><li>Thousands of residents remain under evacuation orders</li><li>Approximately 800+ structures have been destroyed, and thousands more are threatened</li></ul><div class="twitter-tweet" style="display: flex; justify-content: center" data-twitt-post-id="2084640508320854421" src="https://x.com/WeatherNation/status/2084640508320854421"></div>The Governor of Washington, Bob Ferguson, has declared a <a target="_blank" rel="noopener noreferrer nofollow" href="https://governor.wa.gov/news/2026/governor-ferguson-declares-statewide-wildfire-emergency-issues-statewide-burn-ban">statewide wildfire emergency</a>, including a statewide burn ban due to the current drought conditions, high temperatures, and high winds.<h2>Forecast Ahead</h2>Forecast winds are expected to ease through tonight, but active fire behavior will likely continue in these areas. Red Flag Warnings are in place for portions of the Northwest and Northern Four Corners.<img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-05 083614-1785940606283.png">Residents should have a go bag packed and an evacuation plan in place in case evacuation orders expand into their area.

Temperatures are feeling cooler across the plains today! Enjoy it...because it won't last long. Temperatures will begin to warm up again, and a few storms remain possible today.The Storm Prediction Center has issued a MARGINAL (level 1 out of 5) risk for severe thunderstorms along the front across Missouri, central Illinois and southern Iowa (above). All threats look possible, including Isolated tornadoes will be for portions of Illinois and Missouri.<img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-05 083210-1785940339413.png">Storms have already fired up across the central Plains and will continue along the frontal boundary through tonight.

<h1>Pacific</h1>Genevieve formed last Friday south of Acapulco, Mexico. Chewing up loads of warm water, Genevieve rapidly intensified into a Category 5 hurricane; after moving into cooler waters, it started weakening and is back to a tropical storm. Luckily, the storm will stay away from land. However, choppy waters and rough surf can be expected from the coast of Mexico up to Southern California.<img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-02 132115-1785698498667.png"><h1>Atlantic</h1>All remains quiet in the Atlantic for now. Saharan dust is working it's way across the ocean. As waters continue to warm into early fall, stay vigilant! The tropics can create systems quickly this time of year.

Planes lined up in hopes of a timely departure out of Denver International Airport Monday. Unfortunately, high winds made that a difficult task. Especially for Southwest Airlines Flight 203 bound for Las Vegas. Winds are to blame for a minor accident as the plane collided with a piece of ground equipment. Gratefully, there were no injuries.

Winds gusting near 50 mph limited the runways available for take off. According to our affiliate, <a href="https://koaa.com/news/covering-colorado/2019/01/07/wind-blamed-for-minor-accident-and-delays-at-denver-international-airport/">KOAA</a>, delays were at least 15-30 minutes. However, as runway congestion increased, both outbound and inbound flights could be further affected.

High wind warnings are in effect for many parts of Colorado, with westerly winds between 30 to 40 miles per hour and gusts up to 65 mph.
