OptionalbaseOverride the AWC base URL. Defaults to DEFAULT_AWC_BASE_URL.
This is the supported seam for browser use. The AWC API does not send
CORS headers, so a direct cross-origin fetch from a browser is blocked
by the user agent. Point baseUrl at a same-origin proxy you control (a
reverse proxy or an edge function that forwards to AWC and returns the
upstream body) and the fetch* functions work unchanged from the browser.
It is equally useful for pointing at a mirror during development.
OptionalhazardRestrict the response to SIGMETs of the given hazard type.
OptionalsignalAbortSignal used to cancel the underlying HTTP request.
Options accepted by fetchSigmets. Extends FetchWeatherOptions with the optional
hazardfilter supported by the AWCairsigmetendpoint.
