Active weather warnings for New Jersey

# New Jersey Natural Disaster Report

**RISKWATCH ALERT - RIP CURRENT STATEMENT IN EFFECT:** The National Weather Service Mount Holly has issued a Rip Current Statement for New Jersey coastal areas including Eastern Monmouth, Atlantic County, Cape May, and Ocean County beaches, effective through 8:00 PM EDT today (May 16). Dangerous rip currents are expected to sweep swimmers away from shore into deeper water. With water temperatures in the 50s, rapid hypothermia poses serious risk to anyone immersed. Beachgoers in popular areas like Seaside Heights, Atlantic City, Cape May, and surrounding coastal communities should exercise extreme caution and avoid entering the water if possible. Strong swimmers are urged to stay out of the ocean, and those who must enter should swim near lifeguard stations and avoid fighting rip currents by swimming parallel to shore.

Flow report FAQ

About New Jersey streamflow

Where does the New Jersey streamflow data come from?

The U.S. Geological Survey National Water Information System. USGS streamgauges report continuously (every 15 minutes) and the data is the canonical real-time record for U.S. rivers. Snoflo pulls the latest readings and joins them to a 7-day NOAA weather forecast for each station.

What is cfs?

Cubic feet per second — the standard unit for streamflow. One cfs is about 7.5 gallons per second. Small creeks run at single-digit cfs; the Mississippi at hundreds of thousands.

What does Gauge Height mean?

The water level at the gauge in feet above the reference datum. Used together with discharge to track river state. Flood stage and runnable levels are typically expressed in gauge height (e.g., "flood at 16 ft").

How fresh is the New Jersey data?

USGS streamgauges report every 15 minutes; Snoflo re-pulls throughout the day. The AI briefing regenerates daily.

Can I get a flow alert for a New Jersey gauge?

Yes. Save any USGS gauge as a favorite in the Snoflo iOS app, set a discharge or stage threshold (e.g. "alert me when discharge crosses 2,000 cfs"), and you'll get a push the moment it crosses.

Is this a substitute for an NWS flood warning?

No. Snoflo is informational. For flood life-safety decisions always follow guidance from your local NWS forecast office and state emergency management. Snoflo data is one input among several.
