About Crew Weather

Crew Weather is a free GO/NO-GO weather decision tool built for construction crews, excavation teams, and outdoor workers. It blends 8 global models (ECMWF IFS, ECMWF AIFS, GFS, ICON, JMA, GEM, UKMO and CMA), with the HRRR layered over the first 18 hours, with weights learned from daily checks against the Truckee airport station. Over the last 30 days the blend beat every individual model on highs through day 5, overnight lows and sustained wind; live scores are on the Accuracy tab.

New to the calls? Read how GO, CAUTION and NO-GO weather calls work, including the mountain jobsite limits. Features include climate-zone-aware crew thresholds, projected GO/NO-GO status for each day in the 16-day forecast, adaptive precipitation display (rain chance → thunderstorm probability → precipitation volume), heat stroke and freeze warnings, NWS severe weather alert integration, live traffic cameras, and contractor field calculators. Works for any US location by ZIP code.

Built by Errol Kerr, a construction professional and Olympic athlete.

About This Tool

errolkerr.com/crew-weather is a free GO/NO-GO weather decision tool built for construction crews anywhere in the US. Created by Errol Kerr, an excavation foreman at Ruppert Inc., it displays real-time GO, CAUTION, or NO-GO badges based on climate-zone-aware thresholds for wind speed, temperature, precipitation probability, and lightning risk. Enter any US ZIP code to get a crew briefing with thresholds auto-tuned for your region (mountain, desert, southeast, northeast, pacific coast, or plains). The tool uses the same 8-model ensemble forecast as the full weather intelligence platform, with hourly breakdowns and thunderstorm projections. Designed for foremen and crew leads who need a fast field-ready weather call.
