Flash Flood Warnings were issued for:

• Hunterdon and Somerset counties in New Jersey until 1:15 PM.  
• Mercer and Ocean counties in New Jersey until 2:45 PM.  
• Brooklyn, Queens and Nassau County in New York until 3 p.m. 
• Monmouth and Middlesex counties in New Jersey until 3:15 PM.  

The high heat may have come to an end, but a very humid airmass remains in place. As a result of the high levels of atmospheric moisture, the threat of heavy rain and thunderstorms will remain in place through Monday.

Torrential downpours are the greatest concern for this event, and rainfall rates could reach 2 inches per hour at times. This is why the flood risk is elevated. The heavy rain and storms will come in waves, with a particularly heavy round expected in the very early hours of Monday morning. Subsequent rounds will then continue through Monday.

The rain and thick cloud cover will keep temperatures on the cool side for Monday, with the high only reaching the lower 70s.

Rainfall totals so far  

Although the heaviest rain is anticipated Sunday night and Monday, showers could linger through Tuesday afternoon. Final rainfall totals from this event are looking to average between 3-4 inches. Some locales may receive higher totals. 

Temperatures will return to the mid and upper 80s after Tuesday.  

City officials on the inclement weather

New York City Mayor Zohran Mamdani and city emergency management officials urged New Yorkers to be ready for heavy rain, thunderstorms and possible flooding Monday.   

"City workers are doing everything possible to prepare for this storm -- clearing catch basins, inspecting flood-prone neighborhoods, reaching out to New Yorkers living in basement apartments and positioning emergency response teams across the five boroughs," Mamdani said. 

"As we've seen in recent storms, flash flooding can develop quickly and create dangerous conditions with little warning," said New York City Emergency Management Commissioner Christina Farrell.
