Hydrologic Outlook issued February 23 at 3:48AM MST by NWS Missoula MT

ESFMSO

Where: Powell, Deer Lodge, and Silver Bow Counties in Montana and
Lemhi County in Idaho.

What: A significant warm up will continue through Monday, February
24. High temperatures will reach into the 40s, with overnight
temperatures near or above freezing. Rapid lowland snowmelt will
lead to ponding of water in low lying areas, especially in areas
of poor drainage and/or in basements/crawlspaces. Ice jam releases
are also a concern on small streams and/or creeks, and may lead
to localized flooding. Rain showers will bring precipitation totals
up to 0.20 inches across valley areas Sunday into Monday, with
upwards of 0.50 inches in the higher terrain.

When: Through Monday afternoon.
