Floridians, Listen up.
Right now after the 12z GFS and 12z Euro run this afternoon, meteorologists are gathering across the state on how they are going to disseminate information to the public- and notably up the seriousness of their tone in the process.
As we speak, Irma is showing 185mph winds at a Category 5, and it's yet to enter the warmest and most hospitable environment in the Bahamas. Strengthening will continue right up to landfall. By the time it reaches land, it will be an estimated 800 miles wide- dwarfing any hurricane that has approached the Florida coast. Sustained winds of 180mph are possible, with gusts nearing 200mph. Surge will inundate anywhere 12ft or below sea level, which accounts for much of the coastline across the state. It's true that the exact track is unknown at this time. However at 6 days out, model accuracy is vastly improved- and Florida is on the wrong side of the chances of Irma missing landfall.
Understand that the time to formulate a plan starts now. Put best by
/u/supernovasky- the messaging to the public in the coming days will not be "we apologize for inconveniencing your weekend by recommending evac", but rather areas affected will see "evacuate to save your life, danger is imminent".
This is not Matthew. This will be a much larger, more powerful system that will likely end up as a contender for the most powerful hurricane to exist in the Atlantic. It's rare size, pressure, and wind speed combination makes Irma a truly rare system.
Do not underestimate. Please prepare accordingly, and make a plan for evacuation if necessary. Listen to the warnings from local officials and NHC and NOAA. We wish you the absolute best, and will continue to address questions and update information on Irma as it's available.
