SPECIAL WEATHER ADVISORY: As of September 2, 2021 - 4:00 pm

The Township of Pequannock and surrounding area experienced a major flood event over the past twenty-four hours due to the remnants of Hurricane Ida.

At approximately 12:30 pm this afternoon, the Pompton River at Pompton Plains crested at roughly 19.58 feet.  Flood water has begun to recede; however it may recede at a slower rate than previous events due to the pressure being exerted by the Passaic River, which is forecast to crest at 12 noon tomorrow.  

Flood Causes:

  • Rainfall - 4.99 inches of rain fell between Wednesday evening and early Thursday morning.
  • Saturated ground, based upon the recent impact of Hurricane/Tropical Storm Henri
  • Pressure/backflow issues due to major flooding on the Passaic River
  • Additional volume from the opening of the Pompton Gates at approximately 9:50 pm on Wednesday; the Gates remain open 
  • Outflow locations of stormwater infrastructure being at capacity
