For warnings, use official sources

For warnings and every decision about your safety, follow the official agencies and your local emergency officials:

• National Weather Service (weather.gov): tornado and severe weather warnings and all US weather.
• Storm Prediction Center: severe weather outlooks and watches for the contiguous US.
• National Hurricane Center: tropical cyclones in the Atlantic and East Pacific; the Central Pacific Hurricane Center (part of the National Weather Service in Honolulu) for the Central Pacific.
• Joint Typhoon Warning Center and your national meteorological service (for example the Japan Meteorological Agency or the India Meteorological Department) for storms elsewhere.
• USGS Earthquake Hazards Program and your national geological survey for earthquakes.

What these numbers are

HazardPulse publishes probabilities produced by automated statistical and machine-learning models from public data. Where a model’s uncertainty range is narrow enough to inform, we show it beside the number; every range a model produces is in the API, and where a model produces none, we show the single number. No model predicts natural hazards perfectly, and HazardPulse does not guarantee the accuracy of any individual forecast.

HazardPulse does not issue official forecasts or warnings and does not replace the USGS, NOAA, the NWS or any government agency. Its forecasts must not be the sole basis for evacuation, sheltering or any emergency-management decision.

How to read a forecast

A 30% chance means the event is expected in about 3 of every 10 similar situations, and not in the other 7. A low chance is not a promise of safety, and a high one is not a certainty.

Read a number with its window and its place. The three forecasts cover 30 days, 24 hours and 60 minutes, so their numbers cannot be compared with each other, and the same percentage can be usual for one place and exceptional for another.

Limitation of liability

HazardPulse and Coherence Energy Labs provide this service “as is”, without warranty of any kind, express or implied.
