Relative humidity changes with air temperature. Compare it with dew point to understand how two outdoor forecasts can have different moisture content, then keep indoor readings separate.
Severe weather safety guides
Use official alerts, local instructions, shelter or evacuation decisions, and household fallbacks to prepare for dangerous weather.
Sleet reaches the ground as ice pellets; freezing rain reaches it as liquid and freezes on contact. Use the forecast timing, impacts, and local instructions to decide what to postpone and what to check at home.
Turn flood watches, warnings, rising water, road closures, and local evacuation messages into clear household actions, safer routes, and an early-leave plan.
Choose a tornado shelter location, understand watches and warnings, plan for manufactured homes, apartments, vehicles, pets, accessibility, and post-storm hazards.
Understand winter storm watches, warnings, and advisories, why local criteria vary, where to read the full alert, and which household actions belong at each stage.
