Hurricane Ian hits New Jersey: How much rain has fallen? Is there flooding?

Cars slowly head home down Leonardsville Road in Middletown as the first of the heavy rain arrives on September 1, 2021

After blowing through Florida and up the East Coast, the remnants of Hurricane Ian have made it to New Jersey. The storm, which landed on the west coast of Florida as a Category 4 (but on the cusp of a Category 5), is now classified as a post-tropical storm.

As of Saturday morning's forecast, the wind and rain from the now post-tropical storm had hit New Jersey, with the storm proper over North Carolina. The heaviest rain is expected to occur this morning and will taper off by mid-afternoon. According to the National Weather Service forecast, coastal areas can expect rainfall totals of 2 to 4 inches through early Tuesday, as what's left of Ian continues to move very slowly north.

There are also chances of coastal flooding. While there are flooding concerns, the National Weather Service is not projecting anything major like what was seen in Florida or Puerto Rico. Coastal cities are most likely to be impacted by flooding.
