Flood watch issued
Archived — this story has rotated out of today’s deck. It is kept here in full.
The gist
Flood watches were issued across multiple US regions, from Utah and Glacier National Park to Oʻahu.
The alerts signal heavy rain and flash-flood risk for residents and travelers in those.
Background
Multiple flood watches appeared across different parts of the United States, each tied to separate weather systems. In southern and central Utah, the National Weather Service issued a watch from Sunday morning through Sunday evening, while most of Southern Utah was under a watch for Sunday, excluding St. George. At Glacier National Park, forecasts of 1 to 2 inches of rain — and 2 to 4 inches in the mountains along the Continental Divide — prompted a preemptive closure of the alpine section of Going-to-the-Sun Road. In Hawaiʻi, a flood watch remained in effect for Oʻahu with 3 to 6 inches of additional rain possible, and a watch was also issued for the Ohio Valley.
