Weather SlateWatch and warning are different messages
For severe thunderstorms, a watch means the conditions support the possibility of severe weather in and near the watch area. A warning means severe weather has been reported or indicated and calls for protective action. Read the NWS explanation and the instructions in the actual alert.
Do not use this distinction as a reason to wait when a threat is already apparent. Different hazards have different guidance, and the full official message matters more than the label alone.
Read beyond the headline
- Location: is your specific place in the affected area?
- Timing: when was the alert issued, and when does it expire?
- Hazard: what is expected, observed, or indicated?
- Action: what does the issuing authority say to do?
Recheck for updates or cancellations. A saved screenshot of a warning can become outdated even when its text remains readable.
Weather Slate’s alert work
Weather Slate’s official-alert display and notification work remain part of pre-launch development and validation. Existing alert work uses the last current location updated while the app is open; saved places do not automatically become push-alert subscriptions.
This differs from planned rain-timing notifications. This website does not claim that app alert delivery has completed launch validation or that a notification will always arrive.
Safety should not require Plus
Safety-based weather information stays free. Optional convenience or personalization features must not be described as a requirement to see severe-weather safety information.
Weather Slate is not an emergency authority. Keep official channels available, including the National Weather Service and local emergency instructions. Do not rely on an app notification, a radar color, or a comfort score as your sole safety source. Support email is not monitored for urgent weather response.
