New York City is bracing for a blistering midweek heatwave that will push temperatures up to 98°F on Wednesday, with heat index values climbing near 100°F. This dangerous heat is accompanied by a growing threat of afternoon and evening thunderstorms, which could disrupt travel across major routes like I-87 and the FDR Drive. The National Weather Service has issued a Hazardous Weather Outlook and Extreme Heat Warning, which remains in effect until 8 p.m. Tuesday.
On Wednesday, temperatures are expected to remain in the mid-90s, with a high heat index making it feel even hotter. Scattered thunderstorms are expected to develop after 2 p.m., bringing flash flood risks and the possibility of lightning through the evening. Areas like Queens, Staten Island, and parts of Westchester and Rockland counties are at a higher risk of severe weather.
What You Need to Know About the Heat and Thunderstorms:
As the heat wave intensifies, drivers should prepare for potential delays, especially during the evening commute, due to flooded roads and possible ponding on highways. The city’s Emergency Management Office is urging residents to avoid being outdoors between noon and 4 p.m., when the heat will be at its peak. Those who need to be outside should drink plenty of water, wear light clothing, and take frequent breaks in the shade.
The combination of extreme heat and high humidity will worsen air quality in the city, prompting an Air Quality Alert until 11 p.m. Tuesday. Sensitive groups, including children, older adults, and people with respiratory conditions, should limit their time outdoors to reduce the risk of health issues.
