Rain in the past 24 hours for New Jersey

MRMS radar estimate · the past, not a forecast

Most anywhere in New Jersey: 1 to 1.5 in

MRMS estimates 1 to 1.5 in fell at the most, somewhere in the state in the 24 hours to 04:00Z.

The highest cell anywhere in the state, from its outline; not every point in it.

When: 16 Oct 04:00Z to 04:00Z: the 24 hours MRMS summed. Written 04:08Z.
Limits: Radar alone, not corrected to rain gauges: it can be too high or too low, most far from a radar, in mountains, and where hail or melting snow brightens the echo. It says nothing of what will fall, and is not a flood warning.

Forecast details

NOAA’s Multi-Radar Multi-Sensor system (MRMS) mosaics every radar into one estimate of the rain that fell, a grid about 1 km across, which this page samples every 0.05°, about 5 km. This is its radar-only estimate, written every hour. River Forecast Centers make a slower estimate corrected to rain gauges; this is not that. MRMS products.

River flooding

4 gauges in flood in New Jersey, observed or forecast.

Minor flooding New Jersey Atlantic Coast at Atlantic City (ocean front) (IN MLLW), NJ (forecast)
Minor flooding Barnegat Bay at Barnegat Light (IN MLLW), NJ (forecast)
Minor flooding Cape May Harbor at Cape May Harbor (IN MLLW), NJ (forecast)

And one more gauge in flood.

A gauge measures its river at that spot; it does not say whether a particular road or neighbourhood floods. Flash flooding is in the warnings.
