Beaches at Singer Island have been closed for two days due to numerous shark sightings.
Every year at this time, sharks of just about every variety – spinner, reef, hammerhead and bull sharks – follow schools of migrating fish along the Florida coastline.
Double red flags are normally posted to warn swimmers of the danger. The risk is even greater in the morning and late afternoon hours when the sharks normally feed.
Dozens, if not hundreds, were seen swimming very close to shore Wednesday and Thursday. Many were cruising in just three to four feet of water.
Lifeguards identified the vast majority as spinner sharks but a few tiger sharks were in the mix as well.
