The most recent satellite image of Lake Okeechobee’s blue-green algae bloom shows it grew over the weekend after falling to 30 percent coverage earlier this month.
A Sunday image shows about 40 percent of the lake infected with the cyanobacteria. That’s about 220 square miles.
Sachi Mishra, a satellite oceanographer with NOAA, said the increase could be because of calm winds helping the algae accumulate nearer the surface where they are easier for the satellite to see.
Mishra said despite the 10 percent increase in coverage, she generally thinks the bloom is receding. It covered 90 percent of the lake on July 2.
