<p style="text-align: justify">The National Hurricane Center has upgraded the chance for tropical formation to<strong> "medium"</strong> in orange. There's about a 30% chance in the next 48 hours for formation, and a 40% chance in the next 7 days for the North Atlantic, Caribbean Sea, and Gulf. This area is denoted the title AL93, or Invest 93L.</p><video src="https://media.weathernationtv.com/app/uploads/2025/07/07-14 rse bams3k 18z-1752548746937.mp4" controls="true" width="100%"></video><h1>Forecast Models</h1><p>Since this is an area of investigation, there are forecast models, known as spaghetti plots.

<p>It has been 10 days since the devastating floods swept through the Texas Hill Country, and our hearts remain with the communities still recovering. The thought of more heavy rain is the last thing anyone wants to hear right now, but unfortunately, we are monitoring more rainfall. Sunday morning, parts of Texas have seen over 6" of rainfall.

<p style="margin: 0in; margin-bottom: .0001pt;"><span style="font-size: 13.5pt; color: #454545;">Rob grew up in South Florida, where daily afternoon storms and hurricanes piqued his interest in meteorology early on. That interest was fostered by his teachers and his father, who one time brought him onto the roof of their home to watch a funnel cloud move through the Everglades several miles away. Years of filmmaking and tv production in high school gradually pushed him toward broadcast meteorology at Florida State University, where he joined and eventually led the student run daily weather show. After graduating with a Bachelors of Science in Meteorology, he began his career at KESQ in Palm Springs, California before heading to KFSN in Fresno and WLOS in Asheville, North Carolina. He has covered a diverse array of extreme weather events, including haboobs and flash flooding in the desert, extreme snow in the Sierra, hurricanes, and Appalachian ice storms. He also enjoys telling stories and reporting about weather issues.

Severe Storm Risk Pushes into the Great Lakes, Ohio Valley

1-1752289754425.png

Tropical Storm Warnings have been issued in the Windward Islands with Tropical Storm Watches for the Leeward Islands as Isaac moves closer to the Lesser Antilles. Isaac remains a tropical storm with 60 mph winds. The cyclone is located about 420 miles east of Martinique and around 455 miles east of Guadeloupe and continues to move westward.

<img class="alignnone size-full wp-image-96941" src="https://media.weathernationtv.com/app/uploads/2018/09/issac.png" alt="" width="1529" height="870" />

Isaac has been encountering strong upper level wind shear, which will lead to further weakening as the storm approaches the islands. The cyclone is forecast to move across the central Lesser Antilles and into the eastern Caribbean Sea on Thursday, and then move across the eastern and central Caribbean Sea through Saturday.

<img class="alignnone size-full wp-image-96943" src="https://media.weathernationtv.com/app/uploads/2018/09/is-trax.png" alt="" width="1523" height="857" />

Along with tropical storm force winds, Isaac will produce very heavy rainfall. Total rainfall accumulations of 2 to 4 inches with isolated amounts up 8 inches will fall across Martinique, Dominica, and Guadeloupe. In Puerto Rico and the Virgin Islands, 1 to 2 inches of rain with isolated amounts to 4 inches is possible. Up to an inch is anticipated across the remaining Windward and Leeward Islands. This rainfall may cause life-threatening flash flooding.
