Dorian has a lot of loft. That is a powerful eye consolidating energy. That is a really strong storm. The people anywhere in the "cone of uncertainty" needs to leave. 

NOW!

It is a holiday weekend. The traffic is going to be terrible and it is about to get worse. Get off the Florida peninsula for at least the next 3 to 4 days. The state needs to open southbound lanes to northbound traffic if the traffic proves to be a standstill and/or hazardous to itself.

The storm will bring flooding. They need to be well above sea level. The rivers will swell from the approaching storm surge. They should be no less than 30 feet above sea level. Andrew and Katrina were pushing a 20 foot storm surge when they made landfall. In the case of Katrina that storm surge killed at least 1833 in the year 2005.

It is foolish to stay.

The majority of Florida has not experienced a Category 4 storm. Andrew was very south and Katrina was a category one when it passed over Florida. Hurricane Irma did not hit Florida directly off the Atlantic Ocean. A category 5 storm winds are 157 mph or higher. A category 4 storm winds are 130 to 156 mph. Irma hit Florida with maximum sustained winds of 112 mph which is a low category 3. The Keys were hit with higher winds of 150 to 160 and they were devastated.

"Experienced Residents" should not overestimate their ability to ride out this storm.

Kindly recall the RAINS begin at the periphery and not with the eye's landfall. Some of these storms have been huge with diameters 500 miles across or more. Please don't concentrate on the landfall of the "eye" as a definitive "time of day" to be the most prepared for the storm. Kindly remind people the PERIPHERAL RAINS can arrive an entire day or half a day before the eye and in that torrential rains will cause flooding long before the eye arrives. 

Good luck!
