Freeze Nights Arrive November 16–17 in Nampa: Lows Near 36°F Then 30°F Put Exposed Pipes at Risk

Freeze nights arrive in the Treasure Valley on November 16–17, with Nampa lows near 36°F on Monday night and 30°F on Tuesday night, and a 20% chance of wintry precipitation on both nights, in the November 12 forecast. A milder winter still bursts pipes: a single night at 30°F can freeze an exposed line, and the risk sits in unheated garages, vented crawl spaces and sink lines on exterior walls. Rain arrives first — Friday November 13 brings rain with a 90% chance — then temperatures drop. Before the freeze, disconnect hoses from outdoor spigots, shut off and drain outdoor water lines where your home allows, and protect exposed lines in garages and crawl spaces. Know where your main shutoff valve is, and keep it reachable. If a pipe froze and water appears afterwards, or the meter moves with everything off, that is a detection call.
