higher priority than the Local Area Emergency. Dense fog advisory (NPW) – Widespread or localized fog reducing visibilities of or less (up to for marine-based advisories, depending on locally defined criteria) is occurring or is forecast within the next six to 12 hours. Freezing fog advisory (NPW) – Widespread dense fog reducing visibility to less than that occurs in a sub-freezing environment, producing very light glazed ice accumulations on exposed surfaces. Dense smoke advisory (NPW) – Widespread or localized smoke reducing visibilities to or less (up to for marine-based advisories, depending on locally defined criteria) is occurring; minimum visibility criteria may be defined by the accordant NWS Regional Headquarters or local Weather Forecast Office. Dust storm warning (DSW) – Widespread or localized blowing dust reducing visibilities to or less, usually caused by sustained winds of or greater, is occurring or imminent. Gale warning (MWS) – Sustained surface winds or frequent gusts of is either forecast within 24 to 48 hours or is occurring in marine areas. The wind speeds must not be directly associated with a tropical cyclone. Gale watch (MWS) – A gale-force wind event affecting marine areas producing sustained surface winds or frequent gusts of is forecast within the next few days, but its occurrence, location and/or specific timing remains uncertain. High wind warning (HWW) – Strong sustained winds of for one hour or longer, or wind gusts of or greater for any duration that are not associated with thunderstorms are occurring or will occur within six to 12 hours. Wind speeds may pose a hazard to pedestrian and vehicular travel (including toppling or creating flying debris from unsecured outdoor objects, and the risk of pushing cars outside their lane of travel and overturning high-profile vehicles), and cause disruption of electrical utilities and wired telecommunications services (including the downing of electrical lines). Warning criteria may vary by county warning area based on local climatological strong wind frequency. A tropical storm warning implies a high wind warning. High wind watch (HWA) – Strong sustained winds of or greater for one hour or more, or wind gusts of for any duration are expected within 12 to 48 hours. Wind speeds may pose a hazard to pedestrian and vehicular travel (including toppling or creating flying debris from unsecured outdoor objects, and the risk of pushing cars outside their lane of travel and overturning high-profile vehicles), and cause disruption of electrical utilities
