Hurricane Irma will bring severe hurricane conditions to Florida by Sunday.
Florida will see destructive winds, storm surge, heavy pelting and isolated tornadoes.
Florida'south west coast will come across very damaging, if non deadly, storm surge.
Irma will so bear upon parts of Georgia and the Carolinas by later on Sunday into Monday.
Major coastal flooding is possible on the Southeast coast. Inland and littoral areas could see power outages and tree damage.

A threat of rainfall flooding and potent winds capable of triggering power outages, downing trees and peradventure some structural impairment is likely to some degree well inland from wherever Irma tracks in relation to Florida and the Southeast this weekend into early next week.
A forecast model developed by Seth Guikema (University of Michigan), Steven Quiring (Ohio State University) and Brent McRoberts (Texas A&Chiliad) predicted 2 to iii million customers could exist without power from Florida to east Tennessee from Irma's widespread winds. Outages could last days to weeks in parts of Florida.
Here is what we know about impacts for Florida, Georgia, Due south Carolina and North Carolina right at present.
Florida

The hurricane will then keep to touch on much of the peninsula, with severe impacts extending into parts of central and northern Florida.
Life-threatening storm-surge flood will occur forth coastal areas north and east of Irma's path. Hurricane-forcefulness winds (74+ mph) that are capable of causing structural harm and widespread power outages will also occur. Flooding rainfall and isolated tornadoes are threats besides.
Irma has a large wind field so tropical-storm, even hurricane-force winds might reach both the west and east coast of Florida, even outside of the cone. This includes Miami, Naples, Fort Myers, Fort Lauderdale, Tampa-St. petersburg and Orlando.
That National Hurricane Eye (NHC) says that h2o inundation could reach the following levels above ground level in Florida if peak surge coincides with high tide.
Southwestern Florida from Captiva to Cape Sable: 8 to 12 feet
Cape Sable to Boca Raton, including the Florida Keys: v to 10 feet
Venice to Captiva Isle: 5 to 8 feet
Tampa Bay and from the Anclote River to Venice: three to 5 feet
Boca Raton to the Flagler/Volusia County Line: ii to four feet
The Anclote River to the Suwannee River: three to six feet
