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 Pennsylvania

Highest anywhere in Pennsylvania: 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 Pennsylvania, in WPC’s forecast for the 24 hours 18 Oct 00:00Z to 19 Oct 00:00Z. An amount for the area its contour covers, not a total for any one street.
Rain that fell: 1.5 to 2 in at its highest in Pennsylvania, in the 24 hours to 05:00Z, by MRMS’s radar estimate over a grid about 5 km across: a measurement of the past, not corrected to rain gauges.
Rivers: no river gauge in Pennsylvania is in flood or forecast to flood, by NWS’s lists read 05:25Z. Gauges are on larger rivers, not every creek: this is not a sign that nothing can flood.
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.
