The reports are varied right now, but it's almost a done deal that some areas are going to have flooding & lose electrcity. Turn on the Weather Channel & keep it on until they figure out which way, 'Debby' is actually going to go. As far as the boarding up of windows & sandbags at the door that is something to do when you KNOW she is heading your way & is a, hurricane. Your local radio/TV stations will let you know when that happens.
We ALWAYZ have candles, batteries, canned food, ice chests, water & a weather radio at the ready cuz' you never really know. JUST a tropical storm means many things including wind damage & tornados. Don't fret just now but be cautious...keep that weather station tuned!
Best!
