Nine active flood warnings are in effect across five states Saturday — down from 13 Friday and from 20 earlier this week — with Hawaii making its first appearance on the national flood map in this weather cycle as Maine and Indiana cleared.
Hawaii’s entry is the sharpest geographic shift in the story’s 24-hour arc. The National Weather Service has issued warnings covering a broad range of zones spanning Oahu, Maui, the Big Island, Molokai, and Lanai — from the Waianae Coast and Oahu North Shore to Haleakala Summit, Central Oahu, Kona, Big Island East, and Big Island South. The warnings also extend to Kahoolawe and Lanai Mauka, underscoring how widely the moisture event is affecting the island chain. Windward and leeward coasts, interior highlands, and summit elevations are all within the warning footprint. Residents near Honolulu and across the affected islands should follow updated guidance from the National Weather Service as conditions evolve.
Louisiana continues to anchor the mainland flood picture. The Vermilion River at Lafayette’s Surrey Street Gage remains in minor flood stage with no defined end date — the National Weather Service warning stands until further notice. Additional warnings cover St. Tammany Parish and Hancock and Pearl River areas straddling the Louisiana-Mississippi border. At Lafayette, the river’s gauge at 11.5 feet is already triggering minor flooding of Beaver Park, according to the National Weather Service.
Alaska’s spring breakup threat holds. An ice jam near Buckland on the Northern Seward Peninsula remains possible through Sunday afternoon, the National Weather Service warns. The combination of a lodged jam and ongoing snowmelt is raising the risk that rivers, creeks, and streams will exceed their banks. The Middle Yukon Valley carries a separate active warning with similar concerns.
In Illinois, the Kaskaskia River at Carlyle is in minor flood stage and is forecast to remain there through Tuesday evening. The National Weather Service cites impacts beginning at 20.3 feet, including township roads downstream. Missouri and Washington remain on the active warning map, both carrying warnings through multiple days of this extended flood cycle.
Two states featured in Friday’s coverage have since dropped off: Maine, where a Saco River warning had stretched across Oxford, Carroll, and Cumberland counties, and Indiana are no longer in the active count — a sign of improvement across the upper Midwest and New England even as the Pacific and Gulf Coast picture remains unsettled.
The National Weather Service advises motorists in all active flood zones not to drive around barricades or through flooded roads. Updated river forecasts and gauge data are available at water.noaa.gov.
