Gov. Phil Murphy used his coronavirus briefing Monday to issue warnings ahead of Tropical Storm Isaias.

 
He and other state officials say the storm is expected to bring wind, rain and perhaps a storm surge starting Monday night and into Tuesday.

State Police acting Superintendent Col. Pat Callahan says, "2 to 4 inches of rain expected through most of the state, there are some bands that may produce 5 to 8 with the highest winds being tomorrow afternoon, probably around 1 to 8 o’clock."

A flash flood watch has been issued for all 21 counties.

"Starting late tonight, 24-plus hours there’s going to be a lot of rain, we’re obviously watching that for sure, as well as the coastal flooding with the cycle of the moon right now doesn’t help us much either, so we expect coastal and localized flooding as well," says Col. Callahan.

Gov. Murphy and health officials say they are still keeping close watch on new cases of COVID-19 and a still increasing rate of transmission, which could mean the virus is making a comeback.

"I would say that we’re probably on the opposite end of the first wave, I think only time will tell you know where our numbers go," says state epidemiologist Dr. Christina Tan.

As promised Friday, the governor began small reversals in reopening, lowering the maximum indoor gathering to just 25 people.

Religious and political gatherings are exempt from this lowered limit.
