Built-in skills that call National Weather Service API (api.weather.gov).

Uses National Weather Service API (api.weather.gov), ACIS (NOAA Regional Climate Centers), NASA POWER, Element 84 Earth Search (Sentinel-2 L2A)Crop hail claim weather verificationUse when a crop insurance adjuster needs to verify a hail or windstorm claim before a field inspection. Reads severe weather warnings issued over the field around the reported date, station-grid rainfall and temperatures, and satellite vegetation indices before and after the event, then states whether the record supports the claim.5 capabilitiesUse
Uses National Weather Service API (api.weather.gov), NASA POWER, ACIS (NOAA Regional Climate Centers), MapsDairy and livestock heat stress planUse before a hot spell when a dairy farmer, feedlot manager or livestock vet needs an hour-by-hour heat stress plan. Computes the temperature-humidity index from the hourly forecast, compares the week with normal, checks heat alerts, and lists nearby vets and feed suppliers, giving a plan for cooling, feeding and milking times.5 capabilitiesUse
Uses National Weather Service API (api.weather.gov), ACIS (NOAA Regional Climate Centers), NASA POWER, US Energy Information AdministrationHeat wave peak load checkUse when a utility load forecaster or grid operations planner needs to check a coming heat wave against recent demand and history. Reads the hourly forecast and heat alerts for the service area, recent and last-year temperatures, the balancing authority's daily demand from EIA and the climate normal, then flags peak risk days.7 capabilitiesUse
Uses National Weather Service API (api.weather.gov), NASA POWER, US Census Bureau, CMS data.cms.govHeatwave hospital readiness briefUse before a forecast heat event when a county health department, hospital emergency manager or EMS planner needs a readiness brief. Combines the forecast and active alerts with how far temperatures sit above normal, the size of the older population, and the hospitals and nursing homes that will absorb the surge, into one prioritised brief.9 capabilitiesUse
Uses National Weather Service API (api.weather.gov), USFS Wildfire Risk to Communities, US Census Bureau, OpenStreetMapWildfire smoke sensitive-site alert listUse when a county environmental health director decides which schools, care homes and clinics to warn as wildfire smoke arrives. Reads active air quality and fire weather alerts, checks the area's wildfire risk class, counts young children and older adults by tract from Census data, and lists sensitive sites on the map, producing a prioritised outreach list.9 capabilitiesUse
Uses ACIS (NOAA Regional Climate Centers), National Weather Service API (api.weather.gov), NASA POWERAlmond pollination hive move timingUse when a commercial beekeeper is deciding when to truck hives into almond orchards for pollination. Reads growing degree days and temperatures at the orchards, frost and storm alerts, the hourly forecast for bee flight conditions and the month's normals, then picks a delivery window.4 capabilitiesUse
Uses ACIS (NOAA Regional Climate Centers), National Weather Service API (api.weather.gov), NASA POWERInsect pest spray timing by degree daysUse when an independent crop consultant is timing scouting and insecticide applications for a degree-day driven pest. Reads accumulated growing degree days from the biofix date at the base the extension model uses, projects the next week from the forecast, and checks wind and rain for spray windows, then schedules visits.4 capabilitiesUse
Uses US Energy Information Administration, National Weather Service API (api.weather.gov), NASA POWER, CME Group FedWatch and market data, CFTC Commitments of Traders+1Gas storage weather checkUse when a natural gas trader or utility gas buyer, before or after the weekly EIA storage report, asks whether storage is tight going into heating season. Compares the weekly storage build with last year, reads the cold in the forecast for big consuming cities, the futures strip and fund positioning, and gives a balanced view on price risk.8 capabilitiesUse
Uses NASA POWER, National Weather Service API (api.weather.gov), Element 84 Earth Search (Sentinel-2 L2A)Solar fleet underperformance diagnosisUse when a solar asset manager sees a site producing below budget and needs to know whether weather explains it. Compares the site's daily irradiance with its climate normal, checks for smoke, snow or storm alerts over the period, and pulls clear satellite views of the site, then separates weather from equipment causes.5 capabilitiesUse
