<h1>TROPICAL STORM MOKE</h1><p>Just a little over a week after Hurricane Lala impacted Hawaii, another system has formed in the Central Pacific. Tropical Storm Moke formed Friday with max sustained winds of 45 mph and a minimum central pressure of 1002 millibars but hasn't strengthened much since. </p><p>TS Moke is moving at a steady pace to the north-northwest. Moke is expected to bring gusty winds and heavy rainfall to Hawaii. A ridge of high pressure will continue to steer it west. It will gradually strengthen through the weekend, impacting the Hawaiian Islands into next week. Interests in Hawaii should watch model track trends in the coming days.<img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-23 042821-1787480915594.png"></p><p>Early forecasts expect the earliest arrival of tropical storm-force winds Saturday afternoon into Sunday. The probabilities remain low, with the track likely staying south. Heavy rainfall is the greater threat. Moke is expected to produce 3-6 inches of rainfall, and the Big Island can see isolated totals of 12"+ of rainfall. With little room for additional rainfall right now, a flood watch has been issued. <img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-23 042857-1787480950769.png"></p><p></p><h1>HURRICANE LALA</h1><p>While Lala did not make a direct landfall on the Hawaiian Islands, it still brought significant impacts. The Hawaii Department of Transportation reported that parts of Highway 11 on the Big Island were shut down due to flooding. More than 130,000 customers lost power Saturday at the height of the storm. WeatherNation's field correspondent, Jonathan Petramala, was there bringing the views on the ground.</p><div class="twitter-tweet" style="display: flex; justify-content: center" data-twitt-post-id="2088807962383143316" src="https://x.com/WeatherNation/status/2088807962383143316"></div><p>Rainfall totals exceeded 30+ inches in many locations.</p><p><img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-17 101407-1786983268612.jpg"></p><div class="twitter-tweet" style="display: flex; justify-content: center" data-twitt-post-id="2089171101914223009" src="https://x.com/WeatherNation/status/2089171101914223009"></div><p>Lala briefly strengthened to a category 4 hurricane. It is not expected to bring any additional impacts to land as it continues to move over open Pacific waters. It will steadily weaken in the coming days.</p>

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!

Heat, Some Humidity, and Storms for the Southwest the Next Few Days

<p>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. </p><p><img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-23 032445-1787477089898.png">Right on cue, we are seeing 3 areas of potential development in the Atlantic Basin. A tropical wave moving off Africa in the days ahead may have the 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 <strong>medium</strong> chance for development right now.</p><p>The two primary global forecast models are showing development late-week, Both develop the system into a low, but the strength of the system varies quite a bit as the GFS deepens the low more quickly. The system is still only about halfway through the tropical Atlantic by Thursday afternoon, which means any impacts to the U.S. would be another 6-10 days out, at least.<img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-23 032610-1787477175729.png">Stay tuned...this is the time of the year when the Atlantic Waters can get a little rowdy.

Front That Caused Flooding Heading East

Sunday turned out to be quite snowy across eastern North Dakota.  The Grand Forks area picked up over 6 inches by late afternoon.  The potential exists for several inches more before the system winds down Monday.

<img class="alignnone size-large wp-image-89330" src="https://media.weathernationtv.com/app/uploads/2018/03/Alerts-1-728x408.jpg" alt="" width="728" height="408" />

Snow is expected to impact areas from the Northern Rockies into the plains of Wyoming, the Dakotas, and Minnesota now through Monday night.

<img class="alignnone size-large wp-image-89329" src="https://media.weathernationtv.com/app/uploads/2018/03/Sun_11pm-728x408.jpg" alt="" width="728" height="408" />

In addition to the Interstate 29 corridor in eastern North Dakota, heavy snow totals of 6 inches or more will be possible in northeast Wyoming and the Black Hills of South Dakota.  Winds will be brisk, so blowing and drifting will be a concern in open areas.

<img class="alignnone size-large wp-image-89326" src="https://media.weathernationtv.com/app/uploads/2018/03/SnowTotes-728x408.jpg" alt="" width="728" height="408" />

Further east, a wintry mix of snow, rain, and freezing rain will impacts areas of Minnesota, Iowa, and eastern South Dakota.  A light glaze of ice is possible Monday.
