**Important Long Island Update... Heat, Severe Thunderstorms, Tropical Storm Chantal, Flash Flooding, Rip Currents, Potential East Coast Hurricane Next Week**
- First, that storm off the northeast coast is now officially Tropical Storm Chantal, but it's not a threat to land. - A Heat Advisory is in effect for Nassau until 8 PM tomorrow for heat index values of 95 degrees. - There is a high risk of rip currents for the ocean beaches in Suffolk late this afternoon and this evening. - Severe thunderstorms are possible for Long Island late this afternoon into this evening with the potential for heavy downpours (possible flash flooding) and damaging wind gusts. Hail is also possible. While no tornadoes are expected, there is a non-zero chance. Nothing to worry about though. - The Euro is now showing a moderate chance of a tropical storm or possibly a hurricane (low chance) forming just off the southeast coast of the United States early next week and moving up the coast, most likely just offshore. If it becomes a named storm, it will be named Dorian. The area at greatest risk is probably Cape Hatteras, North Carolina. - As for Long Island weather, after the thunderstorm threat later this afternoon and evening, tomorrow will also be hot and humid with a slight chance of a thunderstorm. There is a better chance of thunderstorms overnight tomorrow night into early Friday morning, and then the beautiful weather arrives Friday afternoon into Monday. Low humidity with highs mostly 75 to 80 degrees for the weekend.
