THE AMERICAN INTERIOR — 41 FLOOD WARNINGS TODAY, AND A MODERATE RISK BUILDING FOR WEDNESDAY
A slight excessive-rain risk covers the Central Appalachians — primarily West Virginia and south-west Virginia, expanding into northern North Carolina — where a localized 3 to 6 inches can land on saturated soil, inside a broad marginal that reaches south Florida. The flash-flood focus runs the Ohio Valley, Mid-Atlantic, Southeast and Four Corners, and a broad moderate risk is developing over much of eastern New Mexico on Wednesday. The national feed carries 41 flood warnings, up from 32, with 11 flood watches and zero flash-flood watches, inside 391 active alerts (133 land, 258 marine). The decision-useful number is the antecedent wetness, not the rainfall total.

Two flood problems with different arithmetic.
WHAT THEY'RE SAYING
Heavy rains from a late monsoon surge triggered flash flooding across the Four Corners region, with roads damaged and evacuations ordered in the Navajo Nation. These details align with the official forecast of widespread flood warnings in the American interior and the building risk for Wednesday, while adding early confirmation of localized impacts that broader outlooks had not yet specified in detail.
