NEW YORK – Scorching heat and sweltering humidity choked the tri-state area for the fourth day in a row Friday, bringing threats of storms and poor air quality from smoke from the western wildfires that has made its way into the region one one more time.

More showers and thunderstorms associated with a cold front approaching the metropolitan area will begin to appear Friday afternoon and will continue to move through the region into the night. Severe weather west of the city cannot be ruled out, where stronger storms could produce locally strong gusts and downpours.
The latter could lead to flash floods in particularly vulnerable areas, as well as those that are still saturated with Henri.
A flash flood watch is in effect and was extended by the National Weather Service for all five counties, as well as Rockland and Westchester counties until 2 a.m. Sunday in anticipation of storms. The same surveillance applies to parts of Monmouth, Ocean, Passaic and Warren counties in New Jersey.
Flash Flood Watch now includes NYC, as well as northeast NJ, and parts of the Lower Hudson Valley through Saturday night.
Heavy downpours over a saturated ground later today, and again on Saturday, could lead to flooding in some areas.

More smoke from wildfires in the west has also reached the metropolitan area, just like last month, and will linger during the heat stretch, causing hazy skies. An air quality alert was issued.
Meanwhile, The Weather Authority continues to monitor Tropical Storm Ida, which has prompted a hurricane warning for New Orleans and an emergency declaration for the state of Louisiana.
The storm is pushing through the Caribbean toward an anticipated attack on Cuba on Friday. Forecasters say Ida could be close to the strength of a major hurricane when it hits the northern Gulf Coast. That is expected to happen sometime on Sunday night or early Monday.
