Twenty flood warnings remain in effect across six states — Alaska, Alabama, Indiana, Louisiana, Missouri, and Washington — as rivers across the Gulf Coast drainage basin hold above flood stage and an ice jam on Alaska’s Yukon River continues to threaten the community of Galena with no clear resolution before Wednesday evening.
The National Weather Service has extended warnings along the Pearl River system, where elevated stages show no sign of rapid retreat. The Pearl River near the town of Pearl River is at moderate flood stage, affecting St. Tammany Parish in Louisiana along with Pearl River and Hancock counties in Mississippi. A separate active warning covers the Wolf River above Gulfport, with minor flooding forecast for Harrison County, Mississippi. Extended warnings on both rivers indicate prolonged high water rather than a new surge.
Louisiana carries the largest share of active alerts, with warnings spanning a wide corridor of the state. Rapides, Lafayette, Vermilion, St. Landry, and St. Martin parishes are among the affected areas, stretching from the Red River country in the center of the state south through the low-lying Atchafalaya Basin region. Residents near New Orleans should continue to monitor conditions in St. Tammany Parish, which remains within the Pearl River’s flood footprint across the state line. Further east, the active flood warning in Harrison County remains tied to conditions near Gulfport on the Wolf River.
In Alaska, the National Weather Service says an ice jam confirmed by its River Watch team on the Yukon River near the mouth of the Yukon Flats continues to pose a flooding risk to the Galena area and the broader Middle Yukon Valley through Wednesday evening. High water could affect rivers, creeks, streams, and flood-prone terrain if the jam shifts or releases. Access limitations in interior Alaska make ice-jam events particularly difficult to monitor in real time.
The total warning count — 20 — is unchanged from the previous 24 hours, reflecting an event that has neither escalated to new areas nor begun to unwind. The sustained warning footprint across six states suggests rivers are running high but not rising, the difficult middle stage of a flood event where waiting is the primary task.
The National Weather Service advises: “Turn around, don’t drown when encountering flooded roads. Most flood deaths occur in vehicles.” Caution near riverbanks is urged across all affected areas.
