Milton rapidly intensified to a Category 5 hurricane late Monday morning.
Within hours, Milton strengthened to a Category 2, then a Category 3, then a Category 4 and finally a Category 5.
Milton now ranks as the third-greatest 24-hour wind speed intensification for a hurricane in the Atlantic Basin. (Records are based on data since the satellite era began in the 1960s.)
I’m not sure NOA is responsible for evacuation orders, IIRC they advise state and local governments on who should evacuate and it’s up to the local government to coordinate and reach out to their populations.
