This AccuWeather forecast map indicates that flash-flooding and water-covered roads are possible for much of central and southern New England through Thursday morning.

Even after the remnants of Ida move off the New England coast late tomorrow, much of the region could still be in for some heavy, tropical downpours capable of triggering flash-flooding and deceptively deep ponding on roadways, meteorologists with the AccuWeather forecast center are warning.

Central New England, including Greater Nashua, could see two or three inches of rain in brief amounts of time, meaning residents of low-lying areas and motorists should keep apprised of conditions.

“After the system unleashes a deluge across parts of the Tennessee and Ohio valleys, a tremendous amount of rain will pour down from portions of the central Appalachians to the mid-Atlantic and New England, with the potential for life-threatening and damaging flooding,” AccuWeather stated in a bulletin.

The system will continue tracking to the northeast, where it will likely be a tropical rainstorm by the time it arrives tonight and tomorrow.

Many areas in the Middle Atlantic and Northeast have already had over twice as much rainfall compared to normal for the month of August.

In addition to the heavy rainfall, Ida still has the potential to produce severe thunderstorms and tornadoes along the eastern and southern sides of its track through tonight and early tomorrow.

Farther out in the Atlantic, budding tropical storm Kate was downgraded to a tropical depression Tuesday, but it’s tracking away from land.

Looking ahead, there is a high potential for a tropical depression or storm to form in the far eastern Atlantic over the holiday weekend.
