A forecast is useful when you can connect it to a decision. These guides cover specific hazards and the actions that may change with location, building type and official instructions. Coastal flooding has different access problems from an inland leak; returning after a flood brings hazards that remain after the water falls. Use current warnings and local emergency advice alongside the background planning here.
