Don't worry: It's just not the raging hangover from those seven rum and Cokes you pounded while sweating through the Heat's win last night. Your eyes are not fogged over with Monday-morning regret. Miami really has disappeared under a cloud of noxious smoke.

A huge wildfire in Broward County is to blame for the smoke, which is serious enough that the National Weather Service is warning anyone with breathing problems to stay inside this morning, providing Miami's asthma sufferers the perfect excuse to skip work and sleep off that NBA Finals headache.

The fire, presumably sparked by lightning storms yesterday, is burning near US 27 in Broward and has already claimed about 3,000 acres. The blaze has closed 27 from I-595 all the way north to Palm Beach and has left Broward, Palm Beach, and Dade counties under dense smoke warnings until at least 10 a.m. today.

The NWS urged motorists to drive slowly today and use low-beam headlights while struggling through the pea soup.

Drivers around South Florida have been snapping pics of the surreal start to the week:
