It feels like we’ve been experiencing the outer bands of Halloween for at least a week now, but the heavier squalls reach South Florida this weekend. Experienced locals have stocked their preparedness kits — costume, candy, cocktail mixers — to last for what forecasters predict will be a 10-day event through next weekend and the arrival of Day of the Dead, also known as The Big One. While the atmosphere will be eerie, the weather this weekend is supposed to be perfect if you’re getting out to enjoy, say, the return of the Delray Beach GreenMarket, the Witches of Delray Beach bike ride, Dwyane Wade’s When We Gather Food & Wine Festival or the way-cool LA LOM at the Miami Beach Bandshell.
