THE DEEPEST WATER WILL OCCUR ALONG THE IMMEDIATE COAST IN AREAS OF
ONSHORE FLOW. SURGE-RELATED FLOODING DEPENDS ON THE RELATIVE TIMING
OF THE SURGE AND THE TIDAL CYCLE...AND CAN VARY GREATLY OVER SHORT
DISTANCES. FOR INFORMATION SPECIFIC TO YOUR AREA...PLEASE SEE
PRODUCTS ISSUED BY YOUR LOCAL WEATHER SERVICE OFFICE. NEAR THE
COAST...THE SURGE WILL BE ACCOMPANIED BY LARGE AND DANGEROUS WAVES.

It started raining here in Orlando late last night. The rain has been steady with only a few heavy squalls. No heavy sustained winds to speak of. A few tornado watches in the area but no real bad weather so far. The storm center is about 300 miles from here. Orlando is about 90 miles from the Gulf. So, more rain for us all day. Today is my day off so I can stay out of it and watch from my balcony.

We're drying out a bit. My neighborhood is a few miles east of the I-Drive attractions; Sea World, Universal etc. On a map, Florida Turnpike and Orange Blossom Trail. It stopped raining at noon but has stayed cloudy & breezy....very humid. Right now the heavy weather is east of us, along the coast from Melbourne to Daytona.

I'll say one thing, WAY different than my former homes in Phoenix and Vegas!

Hoping that landfall in the north Gulf will not be too severe.

* APALACHEE BAY...2 TO 4 FT

SHORT DISTANCES. FOR INFORMATION SPECIFIC TO YOUR AREA...PLEASE
SEE PRODUCTS ISSUED BY YOUR LOCAL WEATHER SERVICE OFFICE. NEAR THE
