<p>Lala continues to trace the Southern coastlines of the Hawaiian Islands. The center of circulation passed just south of the Big Island on Saturday. However, with its proximity, very heavy rain and winds gusting above 80 mph still occurred.</p><p>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 as a result of the storm. As the storm moves west-northwest, expect conditions to deteriorate for each island through Sunday.</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>Lala's intensity gradually increased through Saturday. Interaction with Hawaii will likely cause subtle weakening into Monday. However, once it moves into the open waters of the Pacific, expect it to return to Hurricane status.</p><p><img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-16 124105-1786905710671.png"></p><p>The Big Island has now dropped its Tropical Storm Warning. There are still Tropical Storm Warnings are still in place for Maui and all other islands.</p><p><img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-16 064404-1786884259224.png">Tropical storm and hurricane conditions will continue for portions of the state as the system moves through. The higher wind impacts will be felt on the east side of the circulation, as the front right quadrant sees the strongest winds. Tropical storm winds will start spreading west through Sunday. Flooding will likely be the biggest threat with this system, as terrain-enhanced rain could top a foot of accumulation on the Big Island. When heavy rain saturates soils, trees can be toppled more easily. Tropical storm-force winds could have bigger impacts in this scenario.<img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-16 042723-1786876055198.png"></p><p>Beach conditions are also expected to deteriorate as Lala gets closer. Larger swells generated by the system could lead to increasing surf and dangerous conditions along exposed coastlines.<span style="color: rgb(36, 36, 36)">&nbsp;High Surf Warnings are in place for most eastern-facing shores.</span></p><p><img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-16 124215-1786905742587.png"></p>

<p>Last week several rounds of storms moved through areas of the Midwest, producing significant wind gusts and flash flooding. notably for portions of Iowa and Illinois, while Nebraska and Kansas saw their share of impacts as well. Another cold front will arrive shortly after the previous front leaves, sparking a new wave of severe storms, including potential for flash flooding.</p><h1>Forecast</h1><p>Wind shear will increase across the Plains and Midwest as a strong trough moves across Canada, while a cold front will cut into the United States. Along the front on Monday and Tuesday, isolated to scattered severe storms are possible. Instability will be somewhat limited, so severe storms are more likely in the afternoons when daytime heating can add energy to the atmosphere.</p><video src="https://media.weathernationtv.com/app/uploads/2026/08/08-16 rnc new-1786905919924.mp4" controls="true" width="100%"></video><h1>Outlooks</h1><p>As the front dips into the Upper-Midwest on Monday, scattered severe storms will be possible from Sioux Falls down to central Nebraska, with isolated severe storms possible from NW Oklahoma though Minnesota.</p><p><img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-16 124406-1786905904789.png"></p><p>Wind and hail damage are the primary hazards with these storms, but a few tornadoes are possible as well (below).</p><p><img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-16 124413-1786905909274.png"></p><p>As the front swings farther south and east on Tuesday, another round of scattered severe storms is anticipated from Nebraska though western Illinois.</p><p><img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-16 124417-1786905913292.png"></p><p>By Tuesday, heavy rain will become a bigger hazard, with scattered flash flooding possible for areas in dark green (below). Soils are saturated from last weeks rain in many of these areas, meaning runoff or flooding will occur more quickly than normal.</p><p><img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-16 043445-1786876722136.png"></p>

<p>A ridge of high pressure continues to dominate the southern tier of the US, sending storms riding around the ridge through the Midwest and Northeast. Under the high-pressure block, extreme heat and humidity will persist, lasting into next week for some locations.</p><h2>Central U.S.</h2><p>The long-lasting heat dome has triggered heat alerts from Missouri through Florida, with extreme heat warnings in effect (pink boxes, below) along with many heat advisories. Highs will soar into the triple digits, feeling 5-15 degrees hotter with the humidity. Make sure to find adequate ways to stay cool!<img src="https://media.weathernationtv.com/app/uploads/2026/08/Screenshot 2026-08-16 063502-1786883712879.png">Feels-like temperatures remain dangerously hot across the central United States.
