Let me paint a worst case hurricane picture based upon my experience of living in south Florida for 20 years (yes, through Andrew), and my "cat duty" with my then employer, an insurance company. The means I got to exist in an area devastated by a natural disaster and process insurance claims.
Your 1988 house is not built to the current hurricane building code written after Andrew showed how weak the pre-1992 building codes were. Since you are on the top of a hill, storm surge may not get you, but winds can peel your roof like a grape. And if the roof is gone and the windows on the top two floors are blown out, water will be everywhere in the lower floors from the windblown 12" of rain. Hurricanes also spawn tornados, so you want to be able to access that below ground portion of the lowest level.
Internet for your computer? Try no cell service either. Water & sewer will be off line. Two cases of water? Think 20. Freezer full of food, eh. Are you going to feed all the neighbors you let into the garage who no longer have a home?
Where are your valuable papers (birth certificates, passport, bank records, insurance policy), inventory of the household goods for an insurance claim? How much cash is on hand? Banks and ATMs will not be working and neither will any online payment systems. No cash-no gas/food/water. Got flashlights, batteries and a radio? How about a gun? You may be the only lights for miles and bad guys roam after natural disasters. There was a great Twilight Zone episode about this...
Pop the $10,000 for a 27.5 KVA automatic generator and a 500 gallon propane tank (you can bury it it you don’t like the looks). Stock up on water and seriously consider evacuating if a hurricane is coming.It’s just stuff.
If you are in an area hit by a hurricane and remain in place, realize your goal will be survival, not whether your internet or cable comes on and what frozen steak you’ll prepare.
