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.

Sunday briefing for Maryland

Highest anywhere in Maryland: no risk area

This is the outlook, a forecast. Warnings in force here are listed above it and outrank it.

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

When: Outlook valid 18 Oct 12:00Z to 19 Oct 12:00Z: the period it covers, not when storms arrive. This period has not begun.
Prepare: No additional flood preparation is indicated by this outlook.
Rain and rivers: Expected rain: below WPC’s lowest contour (0.01 in) in Maryland, in WPC’s forecast for the 24 hours 18 Oct 12:00Z to 19 Oct 12:00Z. An amount for the area its contour covers, not a total for any one street.
Rain that fell: 2 to 3 in at its highest in Maryland, in the 24 hours to 06:00Z, by MRMS’s radar estimate over a grid about 5 km across: a measurement of the past, not corrected to rain gauges.
Rivers: 1 gauge in flood in Maryland, by NWS’s lists read 06:35Z. Moderate flooding Atlantic Coast at OCEAN CITY INLET (IN MLLW), MD. Not flooding now: observed below action stage (where officials start to act), or not reporting. Listed for its forecast. Forecast issued 16 Oct 17:31Z · crest 4.6 ft at 19 Oct 19:00Z · below flood stage (4 ft) by 19 Oct 23:00Z: moderate flooding. A gauge measures its river at that spot, not whether a road or a neighbourhood floods.
Three sources, each its own window. None is a chance of flash flooding, which is WPC’s outlook above; a flash flood is a warning’s. Gauges in the Live tracker

Official discussion

WPC’s discussion held was issued 00:58Z, and the map 16 Oct 19:17Z: they are different issuances, so the text is not shown with this map until the matching one is read.

WPC’s outlook page

Forecast details

The chance that rainfall exceeds flash flood guidance within 40 km (25 miles) of a point during the valid period, as WPC defines its categories. Marginal is at least 5%, Slight 15%, Moderate 40% and High 70%. WPC’s categories are separate from SPC’s severe-storm categories, and an outlook category is not a warning: a Flash Flood Warning means flooding is happening or imminent. WPC’s definitions.
