Wind and rain windows for site planning.
Not yet available from GMS
Site planning guidance on this page will appear here once GMS publishes it.
Concrete pours, crane lifts, roofing, scaffold work and excavation on Grenada's steep sites all have their own weather limits. The forecast that matters is not the daily outlook but whether a specific window holds long enough to finish the task safely.
Sites carrying loose material, scaffold and temporary structures need a securing plan that can be executed inside the warning lead time, which is much shorter for a severe thunderstorm than for a tropical cyclone.
Plan for the time it takes to secure the site, not the time until the weather arrives.
