GSL Hosts Hazard Services Test

Mar 12, 2021


GSL researchers virtually hosted more than a dozen participants for a Functional Forecaster Assessment Test (FFAT) of new Hazard Services capabilities in late February. They used the Amazon Web Services cloud platform to evaluate the workflow to issue marine and non-precipitation weather products, along with hydrology and winter weather products.

Here are some of the comments from participants:

A “Functional Forecaster Assessment Test” (FFAT), exposes forecasters to a new hazard workflow in an isolated system so they can focus on evaluating how Hazard Services creates watches, warnings, and advisories and how the public would see these hazardous weather products. This FFAT evaluated marine and non-precipitating weather products. Watches and warnings for marine hazards include gales, heavy freezing spray, small craft advisories, dense fog, hazardous seas, and hurricane-force winds. Watches and warnings for non-precipitation hazards cover extreme cold, excessive heat, dense fog and smoke, high winds, and even air stagnation

GSL is developing Hazard Services to modernize how the National Weather Service (NWS) creates watches, warnings, and advisories. The system provides a pathway to operations and enables promising science and technology to be more rapidly incorporated into the warning decision-making process. It is also the vehicle for clear, direct language improvements to ensure more effective information is disseminated to the public.

Congratulations to the Hazard Services Team!
