Experts say heavy rains this spring make it more likely western Lake Erie will see another significant bloom of toxic cyanobacteria later this year.
The bloom's size will ultimately depend on rainfall amounts from now through early summer.
Scientists with the National Oceanic and Atmospheric Administration have issued their first forecast of the year for the lake. They're projecting the bloom will be more severe than last year, which saw a relatively mild outbreak.
They don't expect it will match the large blooms that formed in 2011 and 2015 and stretched across the western and central areas of the lake.
Still, researchers say forecasts made this early in the year can change depending on weather patterns in the coming months.
