Call them what you will--sea nettles, jellyfish, @$%*%!--but they can really ruin a day at the beach like ants can wreck a family picnic.
The National Oceanic and Atmospheric Administration has a cool new map in the experimental stage that is is sharing with the public. It predicts where the jellies will be in the Chesapeake Bay today and three days from now.
Right now, it isn't looking too good for you, Choptank River, Point Lookout and Eastern Bay. The Western Shore, on the other hand, isn't looking too bad.
Give it a whirl http://chesapeakebay.noaa.gov/forecasting-sea-nettles/.NOAA says it compiled the near-real time map by combining information about the temperature and salinity jellies prefer along with field observations from scientists and volunteers with the Alliance for the Chesapeake Bay.
The mapping was a collaborative effort of NOAA, the University of Maryland Center for Environmental Science, Yale University and Shannon Point Marine Center.
NOAA and and Maryland Sea Grant paid for the project.
