A Watch, Warning, and Advisory should not produce the same operational response. Preapproved triggers let teams prepare while a hazard is possible and act when dangerous conditions are expected, without inventing policy during a fast-moving event.
\nThe National Weather Service Baltimore/Washington Forecast Office explains that a Watch means a hazard is possible and people should prepare; a Warning means life-threatening weather is expected and people should take action; and an Advisory means a less-severe but still expected condition that can cause inconvenience or travel difficulty. The office links to the local thresholds used for watches, warnings, and advisories in its forecast area. Official products provide hazard information; the organization remains responsible for choosing safe, lawful actions for its sites and people.
\nThis primary page is from one NWS forecast office. Organizations must verify current definitions, criteria, product names, and instructions with the office serving each location. Product terminology alone does not account for building condition, commute exposure, flood route, vulnerable equipment, staffing, or local government orders. A Warning can also arrive with little or no preceding Watch, so plans cannot require an earlier stage as a prerequisite.
\nList location-specific hazards and retrieve the current product descriptions and criteria from the responsible NWS office. For each Watch, Warning, or Advisory relevant to the site, define a small set of actions, decision owner, completion time, employee message, and escalation condition. Use impact and lead time, not the label alone, to determine whether to stage supplies, alter travel, protect equipment, close an area, or activate an alternate process.
\nReceive official information through more than one path and record the source and timestamp used for decisions. Give incident leadership discretion for conditions that develop before a product is issued, while documenting that authority. Run tabletop exercises where a Warning arrives without a Watch, affects only one site, changes timing, or overlaps a utility outage. Revise triggers after local criteria or operations change.
\nKeep the location-to-NWS-office map, current product references, trigger matrix, approval, alert-channel tests, exercise decisions, completion times, and improvement actions. During an event, preserve the official product and timestamp, local authority messages, decision log, and acknowledgments. Review whether each action occurred early enough and was proportionate; do not interpret the absence of harm as proof that an ignored warning was acceptable.
