It got into the low 30's in S. FL last night. Many people in that area don't have heat in their houses, b/c it's not usually necessary. Most also don't own heavy coats. My husband grew up in Sarasota, FL a house w/out a heater (along with jalousy windows, which are very inefficient), and he remembers it being miserably cold when the occasional cold snap would hit.
It's also dangerous for the citrus crops (and other winter crops), which can't tolerate temps below freezing. Plan on seeing elevated prices in the stores...
