Storms near this property

3 since 1998

Regional context, not property-specific evidence. The National Weather Service names Porthill, the town this property stands in, in 3 storm reports between 1998 and 2012: 1 flash flood, 1 hail, 1 flood. No death or injury is recorded in these reports. Each account below is quoted exactly as the forecast office filed it, from the NOAA Storm Events Database, and each date opens the federal record of that event.

When	Event	Place named	Harm	What the report says
July 2012	Flood	Porthill	-	High flows out of Libby Dam in northwest Montana resulted in widespread flooding along the Kootenai River in and around Bonners Ferry and downstream to the Canadian Border. Flooding along the river began on June 25th and carried over through the beginning of July. Damage occurred along the city dikes in Bonners Ferry. Volunteers had to shore up 500 feet of levy behind the Kootenai River Inn to prevent water from spilling in. Water filled sub-surface storage areas of the General Feed and Grain located near the river in Bonners Ferry. Sloughing of dikes downstream of Bonners Ferry was observed as well. This resulted in an extensive amount of water seepage into farm lands throughout the Kootenai River valley. Over 5,000 acres of farm land was damaged resulting in four million dollars in crop damage.
June 1998	Flash Flood	Porthill	-	2.02 inches of rain at bonners ferry and 1.98 inches at porthill. Parker Creek had some flooding
July 2006	Hail	Porthill	-	no account filed
