re: Laura - President Trump visits Lake Charles, Louisiana for Hurricane Response Update

quote:

As of now they do a full advisory (new cone and graphics) every 6 hours, and an intermediate advisory with updated position, winds and pressure every 3 hours. I could be wrong, but I think they might start doing more frequent advisories as the hurricane nears landfall.

they'll up the position update advisories to every two hours or even every hour if a major storm is making landfall

but it's only when landfall is imminent
