Weather and Floods

Our weather hazards vary considerably: we see few violent thunderstorms and even fewer tornadoes, but potentially face everything other than tropical storms. Although our most common hazardous weather is in winter (windstorms, rain, flooding, occasional snow, ice, and severe cold), climate change is bringing us more frequent and more severe weather, as well as changing precipitation patterns.  Extended periods of severe heat can be particularly dangerous in our area as many people are not acclimated and many homes do not have air conditioning.
