One thing that's still not 100% clear on #Idalia is the timing of landfall. It will be determined based on how fast it lifts out of the Caribbean in the next 24-48 hours. Take the 18z GEFS ensemble - we see timing differences ranging from landfalls around 2 am to 8 pm Wed. pic.twitter.com/Hw1fJx2hJj
