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 think you forget, building it stronger once would cost 50% more upfront. Better to build it twice, or three times at only 100% cost each time. That way you can be the lowest bidder every time.
