New York City, New York — New Yorkers are being urged to prepare for a stretch of dangerous weather as forecasters warn that a combination of intense heat, high humidity, and powerful thunderstorms could impact the region through Friday.
The National Weather Service has issued a heat advisory for New York City and surrounding areas, with temperatures and humidity combining to push the heat index into the upper 90s and potentially above 100 degrees Fahrenheit in some locations.
At the same time, meteorologists are tracking a storm system capable of producing severe thunderstorms, localized flooding, damaging wind gusts, hail, and even an isolated tornado.
Heat and Humidity Create Dangerous Conditions
The biggest concern during the next two days will be the combination of high temperatures and oppressive humidity.
While actual air temperatures are expected to remain in the upper 80s and lower 90s, the added moisture in the atmosphere will make it feel significantly hotter. Officials warn that prolonged exposure to these conditions can increase the risk of heat-related illnesses, especially for older adults, children, and individuals with underlying health conditions.
Residents are being encouraged to stay hydrated, limit strenuous outdoor activities during peak afternoon hours, and seek air-conditioned spaces whenever possible.
The heat advisory remains in effect through Friday as forecasters continue monitoring the potentially dangerous conditions.
Strong Thunderstorms Could Bring Flooding and Damaging Winds
Alongside the heat, forecasters say isolated thunderstorms are expected to develop across the New York metropolitan area.
Some of these storms could become severe, bringing strong wind gusts capable of downing trees and power lines, as well as periods of heavy rainfall that may trigger localized flooding in low-lying and poor-drainage areas.
Weather experts note that saturated roads and reduced visibility during heavy downpours could create hazardous travel conditions during the evening commute.
Residents are advised to remain weather-aware and monitor forecasts closely as storm activity develops.
Tornado and Hail Risk Added to Forecast
Meteorologists are also highlighting a low but noteworthy risk of an isolated tornado across portions of the tri-state area.
According to forecasts, atmospheric conditions may become favorable enough Thursday afternoon and evening for a weak tornado to develop within stronger thunderstorm cells.
In addition to the tornado threat, some storms may produce hail and intense lightning.
While widespread tornado activity is not expected, forecasters emphasize that even a brief tornado can cause localized damage and pose serious safety risks.
The highest potential for severe weather is expected later Thursday, when instability and humidity levels are forecast to peak.
Mayor Urges Residents to Stay Alert
New York City officials are encouraging residents to take precautions as the weather event unfolds. Mayor Zohran Mamdani urged New Yorkers to stay vigilant while traveling and remain aware of changing conditions.

“Extreme heat is deadly, so please seek out air conditioning and help your neighbors do the same,” Mamdani wrote on X.
The mayor also warned residents to watch for hazards such as fallen trees, downed power lines, and flooding caused by heavy rainfall.
“Scattered showers and thunderstorms may continue through Friday. Stay vigilant for potential flooding.”
Relief Expected for the Weekend
The good news for residents and visitors is that conditions are expected to improve by Saturday.
Forecasters predict humidity levels will decrease significantly, bringing more comfortable weather across the region just as major events, including FIFA World Cup activities at MetLife Stadium in New Jersey, are set to attract large crowds.
Until then, officials recommend staying informed, avoiding unnecessary outdoor exposure during the hottest parts of the day, and preparing for rapidly changing weather conditions.
