Not quite as formal as your system wildman, but I just sent this to friends and family:

Hi all - It is still VERY early at 5 days out, and lots can change, but as an FYI, it is possible that we'll have a tropical storm in southeast New England by Monday 8a. Keep your eyes on the news, wunderground, or a nerdy weather blog. And of course, give the Wirecutter Emergency Guide a read. Not too late to sharpen your pocket knife, get batteries in your flashlight, buy a lighter, charge your handheld radio, make some Amazon prime purchases and fill up a gas can or two if needed. [Redacted name] and I are slated to be in [redacted], so it could make for a fun drive home. Fortunately this storm will probably be a miss, but it is worth watching. Happy Labor Day!
