We're thinking about renting a place for the week of Sept 8 through the 15th. Someone I work with said the biting flies (greenheads and black flies) are really bad that time of year - like you can't sist out on the beach or on your deck. Is this true? Also - is it still ghastly hot and humid or can we expect some nice weather? He also told me we have greatrer than a 60% chance of being evacuated because of a hurricane. Is he just trying to spoil my plans or is it true? Please advise.
