MRMS radar estimate of the rain that fell, the 24 hours 16 Oct 04:00Z to 04:00Z · Data: NOAA/MRMS. A measurement of the past, from radar alone: not a forecast, and not corrected to rain gauges. Warnings and watches are as of 04:42Z (now), not for the hours the rain fell in.Alaska is outside this map, which draws the conterminous states; its warnings are listed below.

MRMS radar estimate · the past, not a forecast

Most anywhere in Alaska: outside the grid

MRMS’s grid here covers the lower 48 states; Alaska is outside it.

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.

Each feed is judged on its own clock. The masthead’s reading is the site’s publishing health, which is a different thing: a publishing delay does not make a freshly read warning stale, and a fresh check does not make an old outlook newly issued.
