<h1>TROPICAL DEPRESSION MOKE</h1>Just a little over a week after Hurricane Lala impacted Hawaii, another system has formed in the Central Pacific. Moke has weakened from a tropical storm to a depression, with sustained winds down to 35 mph as of Monday morning. Moke is moving at a steady pace to the north-northwest. This storm is expected to bring gusty winds and locally heavy rainfall to Hawaii. A ridge of high pressure will continue to steer it west and away from the islands. Any lingering impacts will decrease after today. <img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-24 035657-1787565430504.png">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 124048-1787510458480.png"><h1>HURRICANE LALA</h1>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.<div class="twitter-tweet" style="display: flex; justify-content: center" data-twitt-post-id="2088807962383143316" src="https://x.com/WeatherNation/status/2088807962383143316"></div>Rainfall totals exceeded 30+ inches in many locations.<img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-17 101407-1786983268612.jpg"><div class="twitter-tweet" style="display: flex; justify-content: center" data-twitt-post-id="2089171101914223009" src="https://x.com/WeatherNation/status/2089171101914223009"></div>As for the rest of the Pacific, we are monitoring multiple areas of interest for tropical development, including Tropical Storm Iselle. Iselle is set to remain out in open waters, but can impact wave heights and rip currents along the West Coast later this week.<img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-24 035802-1787565499119.png">

In addition to the hot temperatures across the Southeastern United States, there is an increasing threat of severe thunderstorms as we head into the week.<h2>Severe Outlooks</h2>On Monday, the SPC has upgraded portions of Coastal Carolina, Mississippi, and Louisiana to a SLIGHT (level 2 out of 5) risk for severe weather. The main threat will be isolated damaging winds and severe gusts, with a lower threat for hail and a tornado or two across both areas.<img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-24 035122-1787565097243.png">On Tuesday, there is a MARGINAL (level 1 out of 5) risk for severe storms along portions of the Gulf and Atlantic coasts, from eastern Louisiana through southwestern South Carolina. Storms are expected to be more isolated in nature, developing within a moist air mass near the Gulf Coast. The main threat will once again be isolated damaging winds.<h2><img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-24 035244-1787565177583.png">Timeline</h2>Storms along the Gulf and Atlantic coasts will favor the afternoon hours through Tuesday, when surface temperatures are at their highest. By Wednesday, we're watching the next front that is expected to push through the region. This could bring a more widespread chance for thunderstorms across the Deep South, as shown in our in-house forecast model.<video src="https://media.weathernationtv.com/app/uploads/2026/08/08-23 rsc rse bams overnight-1787534110387.mp4" controls="true" width="100%"></video>Locally heavy downpours are possible, which could overwhelm some saturated soils. Flash flooding will be possible over the coming days, with multiple shots at storms. <img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-23 191518-1787534128172.png">For more on this forecast, be sure to join us at :10 past the hour during your east regional forecast.

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!

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, we are seeing 2 areas of potential development in the Atlantic Basin. A tropical wave moving off Africa in the days ahead 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.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 2026-08-24 034641-1787564814253.png">Stay tuned...this is the time of the year when the Atlantic Waters can get a little rowdy.

<h1>WHAT TO EXPECT</h1>A strong ridge of high pressure is bringing heat to the south. Storms will develop around this ridge, bringing rounds of severe weather across the plains. Daily storm chances will occur, with the main concerns being damaging winds, large hail, and even a few tornadoes. Through Monday morning, the severe risk continues from Billings to Bismarck and down into Salt Lake City. There is a significant severe threat through Monday, meaning some storms could produce wind gusts of 75+ mph and hailstones up to 2 inches!<img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-23 191013-1787533883536.png"><img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-23 191034-1787533888433.png"><h1>TIMING:</h1>Some storms may have enough fuel to linger into the overnight hours, but as we head into Monday and Tuesday, the best timing for severe storms will be in the afternoon and evening hours with diurnal heating. Some of these storms will also produce localized periods of heavy rain.<video src="https://media.weathernationtv.com/app/uploads/2026/08/08-23 rnw rnc overnight bams-1787533921928.mp4" controls="true" width="100%"></video><h1>CONVECTIVE OUTLOOKS:</h1>The severe chance continues on Monday and again on Tuesday.

A stormy end to the week is taking shape for parts of the eastern U.S., where rounds of thunderstorms will bring torrential rain, localized flash flooding, damaging winds, and tornadoes.&nbsp;Thursday, storms produced significant damage across parts of Delaware and Pennsylvania. In Dover, a tornado hit, causing damage throughout the city. A high school near Lancaster, PA had its roof ripped off. Friday, storm surveys will be performed to assess some of the damage.<video src="https://media.weathernationtv.com/app/uploads/2026/08/VON_082026_RNE_DOVER, DE_DRIVING THROUGH THE DAMAGE IN DOVER_FB_CAITLIN HARVEY_BH_082016-1787279216568.mp4" controls="true" width="100%"></video><video src="https://media.weathernationtv.com/app/uploads/2026/08/VO_082026_RNE_YORK, PA_DAMAGE TO EASTERN YORK HIGH SCHOOL_YORK EMS_BH_082026-1787279282869.mp4" controls="true" width="100%"></video>Showers and storms will linger into early Friday morning over areas of the Mid-Atlantic.

Heavy downpours can quickly overwhelm storm drains, leaving streets, underpasses, and other low-lying areas flooded. Areas that experience multiple storms could see the flooding risk increase as the ground becomes increasingly saturated.<img src="https://media.weathernationtv.com/app/uploads/2026/08/PIC 2-1787274133924.jpg">A cold front moving east will provide the trigger for showers and thunderstorms throughout the day. With plenty of moisture available, some storms will be capable of producing a large amount of rain in a short period of time.&nbsp;<img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-20 080419-1787234676441.png">Friday, the focus for heavier rainfall and thunderstorms is expected to extend from parts of Virginia and North Carolina toward the Delmarva Peninsula and portions of South Carolina.&nbsp;Severe storms could extend all the way down to the Gulf Coast for Friday afternoon and evening.<img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-21 040323-1787306617672.png">The front could linger near the East Coast rather than quickly clearing the region, allowing additional showers and storms to develop into the start of the weekend. Several inches of rain could accumulate in some locations, especially where thunderstorms repeatedly track over the same areas.&nbsp;If a roadway is covered by water, drivers should turn around and find another route. The depth of floodwater can be difficult to determine, and even relatively shallow moving water can create hazardous conditions for vehicles.&nbsp;Tune into WeatherNation TV for more details.

Pea size, baseball size, even grapefruit size?

There are many everyday items that we can use to determine the best estimate of a hail stone.

<img class="alignnone wp-image-90381 size-full" src="https://media.weathernationtv.com/app/uploads/2018/04/hail-size-chart-pics.jpg" alt="" width="630" height="617" />

Pea size hail is ¼" in diameter and hail at ¾" is the width of a penny.

When hail is 1" in diameter, that’s the same size as a quarter and also when hail size is considered "severe" (or large enough to potentially cause damage).

<img class="alignnone size-large wp-image-90382" src="https://media.weathernationtv.com/app/uploads/2018/04/quart-728x408.jpg" alt="" width="728" height="408" />

Some of the most destructive hail that falls measures at least 2" in diameter!

Tennis ball size is 2 ½", baseball size measures 2.75", tea cup size is 3", and softball size measures 4" in diameter.

Did you know hail can be even larger than that?

https://twitter.com/i/status/1258580136699420674

The biggest hailstone ever recorded was near Vivian, South Dakota in 2010, coming in at 8” in diameter!

Just remember -- before you go outside to measure the size of hail that fell in your backyard, wait until the storm has moved far enough away so you can safely make your observation.
