Definition of a watch and Warning
watch:
Watches issued by the National Weather Service (NWS) indicate atmospheric conditions that are conducive to producing severe weather events, suggesting they will eventually appear. It means severe storms are possible but has yet to occur; anyone wearing one should remain attentive to changes and update on changes as necessary; please remember, however, that wearing one does not guarantee severe conditions but serves as a reminder to be ready and up-to-date with weather developments.
Warning:
The warning is defined as the act or process which serves to warn or alert others that something dangerous could be occurring in their area, regardless of their physical appearance.
An alert issued by the National Weather Service (NWS) signals the possibility or presence of severe weather in a particular region, with a warning being an even more urgent and serious warning than watching as people must act immediately to safeguard themselves and their belongings.
An alert’s purpose is to give a warning of potentially severe weather so individuals can take appropriate actions to stay safe in advance of its arrival. In such an instance, people might be advised to seek shelter, leave the area altogether, or otherwise take steps necessary for their well-being to remain secure and remain unharmed by it.
Explanation of when a watch is issued
National Weather Service (NWS) issues watches approximately one hour before severe weather forms. They issue these when atmospheric conditions favor severe conditions like tornadoes, thunderstorms, or hurricanes forming.
As an example, a storm watch could be issued when conditions in an area favor the formation of tornadoes; an alert could also be issued in case severe thunderstorms form that has the potential for producing powerful winds, hail, or even tornadoes; finally, a hurricane watch might also be issued should one be forecast to strike within 48 hours in any particular region.
Be mindful that when engaging in weather watches, individuals must remain prepared and aware of possible severe weather, though this doesn’t indicate it will necessarily come about. Instead, the aim of a weather watch is simply to alert individuals of its possibility while encouraging them to remain informed and ready to act should severe conditions arrive.
Explanation of when a warning is issued
Example of Weather Warning Systems in Use (PDF). A tornado warning could be issued if one was observed and detected on the radar; a severe thunderstorm alert could also be issued if a thunderstorm produced powerful storms, massive hailfall, and possible tornado formation; while a hurricane warning would apply if a hurricane were expected to make landfall within 36 hours.
As part of staying safe, we must heed warnings issued by the National Weather Service or local authorities and follow their guidance. Ignoring their advice could put life and property in jeopardy.
What factors cause alerts?
National Weather Service (NWS) issues warnings when severe weather threatens an area and has already occurred there, warning people of their possible risk and providing guidance as to how best to stay protected.
Warnings are issued whenever severe weather threatens to have a substantial effect on an area, for instance, warnings for tornadoes can be issued if detected or seen on radar in that location; severe thunderstorm alerts would then follow, with powerful gusts of wind producing powerful gusts, large hail or even tornadoes being produced during such an outburst; finally, if hurricane activity is expected within 36 hours it would also trigger one such as those previously discussed above.
Warnings issued from the National Weather Service or local authorities must be carefully observed, with residents taking necessary actions such as seeking shelter, departing the area, or any other necessary precautions immediately when given. When this warning occurs, residents should act swiftly to safeguard themselves and their belongings by either seeking refuge, leaving immediately, or taking other essential actions such as leaving.
Warnings should never be ignored, and must not be disregarded; doing so puts lives and properties in jeopardy, so the public needs to monitor weather conditions closely in case any warnings should come through.
