<p>Isaias ended the late-season streak of no hurricanes in the Atlantic, but how will the rest of the season shape up? Record-breaking wind shear is likely to continue to limit most tropical systems in the Atlantic, but a few more storms are still possible.</p><h3><strong>Tropical Depression Twenty-Two-E</strong></h3><p>Tropical Depression Twenty-Two-E has formed in the Eastern Pacific, south of Mexico. It is expected to strengthen to a major hurricane over open waters. The name to listen out for with this storm once it strengthens is <strong>Vance.</strong></p><p><img src="https://media.weathernationtv.com/app/uploads/2026/10/Screenshot 2026-10-21 095008-1792597812910.png">There is another area of tropical interest brewing west of the Hawaiian Islands.

Taban Sharifi

Tropical Depression Twenty-Two-E Forms in the Pacific

Screenshot20261021094844png-1792597726502.png

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!

<p>Looking ahead to this week, a low-pressure system will drop south from Canada down into Southern California. WPC favors most of the Western United States for above-average precipitation, which is good news after the fires that broke out across Southern California last week.</p><h2>FORECAST TIMING</h2><video src="https://media.weathernationtv.com/app/uploads/2026/10/1021-1792593320825.mp4" controls="true" width="100%"></video><h2>SEVERE STORMS</h2><p>There are two areas to watch out for in relation to severe storms on Wednesday. There is an <strong>Enhanced</strong> risk for severe storms across Central Arizona.

There is also a <strong>Marginal</strong> risk for severe weather across Southern California. Isolated tornadoes and damaging winds will be possible here.</p><p><img src="https://media.weathernationtv.com/app/uploads/2026/10/Screenshot 2026-10-21 083531-1792593335696.png"></p><p>A <strong>marginal to slight </strong>risk for severe weather will stick around through Thursday.</p><p><img src="https://media.weathernationtv.com/app/uploads/2026/10/Screenshot 2026-10-21 053504-1792582517084.png"></p><h2>EXCESSIVE RAINFALL &amp; SNOW</h2><p>The Weather Prediction Center (WPC) has a <strong>slight</strong> to <strong>moderate</strong> risk for heavy rainfall and flooding across portions of the Southwest Wednesday and Thursday.</p><video src="https://media.weathernationtv.com/app/uploads/2026/10/2026-10-21 09-26-09-1792589289048.mp4" controls="true" width="100%"></video><p>Precipitation should really get going on Wednesday, especially in Central and Southern California.

<h1>SETUP</h1><p>An upper-level low broke off from the flow aloft earlier this week. This helped spin up a surface low that will remain largely stationary into Wednesday. That could buy it enough time to acquire subtropical characteristics sometime this week. Regardless, the impacts will be felt, especially along the coasts.</p><video src="https://media.weathernationtv.com/app/uploads/2026/10/2026-10-21 05-44-24-1792583087867.mp4" controls="true" width="100%"></video><h1>IMPACTS</h1><p></p><p><img src="https://media.weathernationtv.com/app/uploads/2026/10/Screenshot 2026-10-18 113555-1792344980113.png"></p><p>High winds with a stubborn low will wear down many beaches along the eastern seaboard. What's of most concern are the beaches in North Carolina, which stick out farthest, and places like Virginia, which will have to endure days of breezy winds agitating the seas. Waves of 10-15 feet can be expected, which will help push a few feet of seawater onshore into normally dry stretches of the coast.</p><p><img src="https://media.weathernationtv.com/app/uploads/2026/10/Screenshot 2026-10-20 050623-1792494397482.png"></p><p>Wind gusts could reach 40-50 mph at times throughout the week as well. The questions about rainfall hinge on the location of the low. At this time, only areas along the coast could get a few showers, with the best chance looking like Wednesday.</p><p><img src="https://media.weathernationtv.com/app/uploads/2026/10/Screenshot 2026-10-21 054357-1792583048244.png"></p><h1>JOSEPHINE? IS THAT YOU?</h1><p>But if the low develops some tropical characteristics, it would need a name. Josephine is the next name on the list in the Atlantic basin. The NHC has started to increase these chances, dubbing it Invest 93-L in its latest update.</p><p><img src="https://media.weathernationtv.com/app/uploads/2026/10/Screenshot 2026-10-21 054250-1792582982885.png"></p><p>Right now, a majority of models struggle to develop the traits needed to qualify as a subtropical system, but that could change. Ultimately, the impacts won't change with or without officially naming it.</p>

<h3>WHAT TO EXPECT</h3><p>A ridge of high pressure will build this week, keeping temperatures above average across the central U.S. Temperatures across the south will run 5°-10° above average, but in the northern Plains and Midwest, 10°- 20° above average! This will make for some warm weather for any fall activities you have planned.</p><h3>NORTHERN PLAINS AND MIDWEST:</h3><p>Temperatures will be quite warm in the coming days for this portion of the country. Most cities will see highs in the upper 60s and 70s! Rapid City normally has an average high of 58°, and on Thursday will have a high of 81°!</p><p><img src="https://media.weathernationtv.com/app/uploads/2026/10/Screenshot 2026-10-21 051638-1792581412613.png"></p><p>As we look ahead through the end of October, there is high confidence that much of the country will remain above average.

<p>Santa Ana winds helped several fires grow quickly on Thursday and Friday around Southern California, forcing a closure on I-5 near Camp Pendleton.

ABOVE: Agatha made landfall as a category 2 hurricane with maximum winds sustained at 105 mph, pressure of 974 mb. Agatha rapidly intensified this weekend into a category 2 hurricane with winds topping 110 mph. It is now weakening (wind wise) as it moves inland and brining heavy rain to Central Mexico.

https://twitter.com/WeatherNation/status/1531697013674242048

Since interacting with the land, maximum winds have decreased to 35 mph with locally higher gusts.

Tropical Storm Warnings are in effect from Salina Cruz to Lagunas de Chachua, Salina Cruz to Boca de Pijijiapan, and Lagunas de Chachua to Punta Maldonado. Additional information in specific areas can be found by <strong><em><a href="https://smn.conagua.gob.mx/es/">clicking/tapping here.</a></em></strong>

Forecasts for Agatha are ceasing today as the storm has weakened significantly from a wind perspective. Damaging rains can still cause trouble in central Mexico, so please make sure you think of all the hazards with a tropical system.
