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.

Saturday briefing for Mississippi

Highest anywhere in Mississippi: 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 01:00Z to 12:00Z: the period it covers, not when storms arrive.
Prepare: A warning is in force here: follow its instructions in Current alerts first.
Rain and rivers: Expected rain: below WPC’s lowest contour (0.01 in) in Mississippi, in WPC’s forecast for the 24 hours 00:00Z to 18 Oct 00:00Z. An amount for the area its contour covers, not a total for any one street.
Rain that fell: 0.25 to 0.5 in at its highest in Mississippi, in the 24 hours to 04:00Z, 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 Mississippi is in flood or forecast to flood, by NWS’s lists read 05:05Z. 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 covers the whole country, not Mississippi alone.

WPC Excessive Rainfall Discussion, Day 1, issued 00:58Z · Data: NOAA/WPC

...THERE IS A MARGINAL RISK OF EXCESSIVE RAINFALL ACROSS PORTIONS
OF SOUTHEAST FLORIDA...

Convection has generally peaked across FL, with the coverage of
heavy rainfall expected to be on the decline overnight. A
localized urban flash flood risk may continue for a few more hours
across portions of the southeast coast of FL where slow moving
cells could drop 2-3" of rain in an hour. Coastal convergence, and
outflow driven convergence from the convection over the center of
state, are allowing for some modest expansion of these slow moving
cells. This activity should also tend to weaken in intensity within
a few hours.

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.
