As more rain falls, thousands without power and flash floods likely in North Jersey

The rain that has prompted flooding across North Jersey all day isn’t going anywhere anytime soon, prompting new warnings about flooding across the region.

Showers and, potentially, more severe thunderstorms are expected well into Monday night. Rain is forecasted for Tuesday and Wednesday as well. The storms have caused flooding and power outages.

Counties to the west, including Morris, are seeing more serious storms and warnings as night falls in North Jersey.

As of 8 p.m., Jersey Central Power and Light had reports of more than 14,400 people throughout the state without power while PSEG is reporting an additional 2,200 outages.

Bob Ziff of the North Jersey Weather Observers said that this is a “typical summer pattern” of “hit or miss thunderstorms”

“Areas that received more daytime heating destabilized the atmosphere, allowing big storms to form,” Ziff said.

As of 6:30 p.m. rain totals included 3.99 inches in Paterson, 3.41 in Butler, 2.2 in Ramsey and North Haledon, and 1.89 in High Point.

Dominic Ramunni, a meteorologist for the National Weather Service confirmed that flash flood warning are in effect for parts of the area and that more showers and the possibility of thunderstorms are to be expected throughout the evening.

Ramunni noted that there have been reports of hail and flooding already on Monday and that things aren’t expected to dry out until after midnight.

He also said that any storms moving through the area have the potential to be severe with strong wind gusts and hail as well as localized flash floods possible.

What about later this week?

Temperatures should remain warm throughout the week, sitting in the low 80s. It will also be quite humid, as a result of the constant rain expected.

The sun isn't expected out until Wednesday, according to the National Weather Service's forecast, but even then it will likely give way to showers, as is expected to be the case through Sunday.
