Locations:
* Willow and Talkeetna
* Rivers, creeks, and streams with headwaters along the western Talkeetna Mountains
Timing:
* This (Monday) evening through Wednesday afternoon. Heaviest rainfall expected late Tuesday morning through Tuesday night.
Rainfall:
* Rainfall totals of 1 to 3 inches Monday through Wednesday likely won't be high enough for widespread flooding, but smaller tributaries draining the Talkeetnas including Willow Creek and the Little Susitna may reach bankfull.
Hydrologic Concerns:
* Many lower locations along rivers such as gravel bars and other spots popular for camping and recreating may become inundated with water with rivers reaching bankfull conditions.
* Heavy rain may result in localized ponding in low-lying areas and locations with poor drainage.
Next Steps:
* Residents along area streams as well as river users and recreators should anticipate higher than normal water levels and are advised to monitor weather and river forecasts.
* Send weather or flooding reports to inws.ncep.noaa.gov/report/ or by calling 1-907-266-5127.
* Reports on river conditions may be sent to the river forecast center by calling 1-907-266-5160.
