On July 18, 2026, flash flood warnings were issued for several parts of New York City and northern New Jersey after torrential rains dropped up to 3 inches of rain within hours, with rainfall rates of 1 to 2 inches per hour. The National Weather Service expanded warnings to multiple counties in northern New Jersey while the Bronx remained under a flood advisory through 3:30 p.m., with an additional 0.5 to 1 inch of rain forecasted.
Heavy rain forced the closure of the Clearview Expressway in Queens in both directions near Northern Boulevard, and standing water caused traffic delays near
the Long Island Expressway and Maurice Avenue. LaGuardia Airport notified passengers of flight disruptions and advised them to check with airlines. Newark Liberty International Airport experienced a ground stop due to flash flooding and severe thunderstorms affecting the region.
NYC Emergency Management advised residents not to enter flooded roads, buildings, or basements, recommending moving to higher ground or floors and calling 911 if immediate assistance is needed. Commuters were urged to monitor updates from the Metropolitan Transportation Authority and 511NY before traveling. Torrential rains overwhelmed drainage systems, and ongoing severe thunderstorms from the southwest threatened additional heavy rain and escalating
flood risks throughout the day.
Transport Infrastructure Impact and Official Advisories
The flooding and intense storms disrupted travel and prompted emergency agencies to advise against unnecessary trips. NYC Emergency Management stated, “Localized flooding reported in parts of NYC. Don’t enter flooded roads or buildings. Stay out of flooded basements. Move to higher ground/floor if needed. Call 911 if you need immediate assistance. Avoid unnecessary travel.” Changing weather conditions may cause ongoing flight delays throughout the day at various airports in the New York City and northern New Jersey area.
