El Niño has been smothering tropical waves in the Atlantic this summer, with three named storms to date but only 16% of average cyclone energy! This doesn't mean the rest of the season will be just as quiet, however, as 66% of all hurricane activity in the Atlantic occurs between August 20th and October 10th.<img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-23 032445-1787477089898.png">Right on cue, an area of potential development is being watched in the Atlantic Basin. A tropical wave, Invest 96L, has moved off of Africa and is now in the far eastern Atlantic. In the days ahead, it may have a better chance to get its act together this week as it moves across the MDR (main development region) in the Atlantic, between Africa and the Caribbean. There is a medium chance for development right now.<img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-26 082923-1787754577131.png">The two primary global forecast models are showing development late in the week. Wednesday morning models are showing some decent confidence in the overall outcome. Both the intensity and the placement being similar gives forecasters a little more confidence in what we're seeing. <img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-26 083010-1787754624501.png">Stay tuned...this is the time of the year when the Atlantic Waters can get a little rowdy. The next system to gain tropical storm status in the Atlantic will be named Dolly.<img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-22 081921-1787408368849.png">

Atlantic Tropics: Chance of Development in the MDR

Screenshot20260826082822png-1787754513064.png

<h1>ISELLE</h1>Tropical Storm Julio formed Tuesday morning in the Eastern Pacific and was absorbed by Iselle Tuesday evening. Iselle has weakened a touch but still remains a tropical storm but has struggled to maintain consistent thunderstorm activity. <img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-26 082025-1787754038726.png">The only tangible effect from Iselle could be the anrgy sea it churns up. Waves from these systems could make it far enough north to impact the coast of southern California. Interests there should watch for a higher rip current risk through the end of the week.<img src="https://media.weathernationtv.com/app/uploads/2026/08/icnreasing surffff-1787694792706.png">With multiple other areas of development, we expect additional storms to come off the factory line and move west and northwest into the Pacific. El Niño is traditionally very active for the Pacific basin, and this year has proved it. Lala continues as a Tropical Storm northwest of the Hawaiian Islands. Moke is post-tropical and fizzling out.<h1>OTHER SUSPECT AREAS</h1>There are more waves behind Iselle (top). The most likely area to earn a name off of the Eastern Pacific list would be Invest 93-E. Thunderstorm activity ramped up Tuesday night and looks like a much healthier wave. <img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-26 082350-1787754289778.png">Taken with a grain of salt, the GFS model has a small gathering developing in the Pacific on Saturday and Sunday. After dissolving Iselle, we could have 4 different areas loitering together this weekend. <img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-26 082606-1787754438851.png">Click here for more on what is happening in the Atlantic Basin:<a target="_blank" rel="noopener noreferrer nofollow" href="https://www.weathernationtv.com/news/atlantic-tropics-watching-several-areas-strong-tropical-wave-next-week"> Atlantic Tropics.</a>

Multiple Areas to watch in the Pacific Basin

High pressure has returned to the Southwest. Extreme Heat Warnings (in pink) have been issued for cities including Los Angeles, Phoenix, Las Vegas, Tucson, and Yuma. Heat Advisories (in orange) have been issued across the Inland Empire of California.<img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-26 081920-1787753972248.png">We started the week with plenty of triple digits across the Southwest; even Los Angeles is expected to see triple digits over the next few days! Most of the Southwest, which is normally hot, will have many cities running above average.<img src="https://media.weathernationtv.com/app/uploads/2026/08/erffffff-1787707011338.png">Los Angeles in particular is of interest because it has been nearly 2 years since we have hit the century mark. The last time LA was over 100 degrees was September 5th of 2024!<img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-24 193702-1787621943327.png">The added boost in temperatures comes by way of an offshore wind known as a "Sundowner wind" which will keep things breezy overnight. That wind will also up the fire weather in the area, with an elevated threat for fire weather from the Storm Prediction Center<img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-26 081825-1787753926904.png">

Strong storms came through the plains on Tuesday. Damaging winds and large hail were the main concerns. Clayton, NM saw a wind gust of 84 mph! The severe threat continues into the overnight hours and into Wednesday.<img src="https://media.weathernationtv.com/app/uploads/2026/08/fddffss-1787706914451.png">Severe chances continue into the evening and overnight hours with damaging winds and large hail as the main concern. There is a significant wind threat across the western Plains and Front Range; in blue is where we could see 75+ mph winds. In green is where we have an isolated tornado threat near the surface low in northern Minnesota and Wisconsin.<h2><img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-25 081430-1787667285067.png">SPC Wednesday</h2>The severe threat continues across the Front Range once again on Wednesday<img src="https://media.weathernationtv.com/app/uploads/2026/08/more storms wedn-1787706161607.png"><h2>Forecast Timing</h2>As the front moves east, new development will be possible as we run into more daytime heating and Gulf humidity. Along the Front Range, upslope flow combined with daytime heating will help storms develop.<video src="https://media.weathernationtv.com/app/uploads/2026/08/overnissss-1787706020519.mp4" controls="true" width="100%"></video>For more info on the central regional forecast, tune into WeatherNation at :30 past the hour, every hour.
