The northeast is bracing for further heavy rains on Monday after severe storms last week that inundated New York’s subways and submerged streets.
The region was subsequently hit by Tropical Storm Elsa, experiencing even more precipitation.
A weak storm system will slowly lean south on Monday and Tuesday, dragging storms along the northeast coast and bringing another threat of significant flooding.
“It looks like the heaviest precipitation is likely to occur in eastern Pennsylvania and east toward the greater New York metropolitan area, where unequal totals of 1 to 3 inches are possible through Wednesday. morning, ”the Weather Prediction Center said.
Flash flood watches have been issued by the National Weather Service from northern New Jersey to the southern edge of Maine, including New York and Boston.
Some watches are in place until Tuesday and Wednesday as the rain is expected to be slow.
“Heavy rains over a short period of time can cause streams and streams to rise quickly and overflow their banks. There is also the potential for flash flooding in more urbanized areas and poorly drained areas, ”the Mount Holly, New Jersey Weather Service said.
Flood watches cover the northeast until mid-week.
The forecast center on Monday issued a moderate risk of heavy precipitation over the tri-state area of New York, New Jersey and Connecticut due to two rounds of precipitation resulting in significant flood threats.
Heavy rains will fall on soils already saturated by previous rainfall from last week, resulting in more runoff and a higher risk of flooding.
Monday night is the biggest flood concern in the tri-state region, due to thunderstorms moving through the region dumping 2-5 inches of rain.
Elsa’s rainfall last week was 300 percent or more than average according to the WPC, and New York City subway scenes filled almost to the brim with floodwater as pedestrians waded through trash bags, trying to stay dry is not out of the question again.
Up to 5 inches of precipitation is possible in parts of the northeast through Wednesday.
New York’s monthly precipitation total is already 4.8 inches for the month, compared to the 1.5-inch average for July monthly precipitation. This is a record for the highest amount of precipitation recorded so far in July.
Boston is included in a slight risk of excessive precipitation and could see nearly 2 inches of precipitation in some areas.
July has already been humid for the city with rainfall this month, making it the wettest July fifth on record.
Monthly precipitation in Boston hit a record 7.6 inches after seeing rain every day since the start of the month. The average monthly precipitation for the region is 1.2 inches.
By Wednesday, the low will push a warm front northward and leave drier weather for the northeast. The dry spell won’t last long though, as the end of the week could bring even more rain to the soggy area.
