The remnants of the most powerful hurricane ever in the western hemisphere will have an effect on New Jersey later this week.

The National Weather Service warns of 1 to 3 inches of heavy rain and thunderstorms  from what is left of former Hurricane Patricia could cause flooding in poor drainage areas and where fallen leafs block drainage areas on Wednesday.  Northeasterly and easterly winds of 15-20 mph could also help bring coastal flooding to shore areas.

The threat of coastal flooding is of concern to some shore towns recovering from heavy beach erosion from a nor'easter earlier this month. Atlantic City saw serious erosion in its north end and erosion was especially bad at the southern end of Sea Isle City and the north end of North Wildwood. Mantoloking, Toms River, Brick and Long Beach Island had major erosion as well.

"Absolutely not a huge, devastating storm by any means, but still an important one that NJ residents need to take seriously," said meteorologist Dan Zarrow.

Patricia made landfall on Friday night along the western Mexican coast as a category 5 hurricane with 200 mile-per-hour winds and torrential rains. Southeast Texas was also drenched with heavy rains during the weekend with 8 inches of rain falling in some areas.
