A red tide may be seen across parts of the southwestern Florida coast through Thursday, prompting the Tampa National Weather Service to release a Beach Hazards Statement Tuesday.
The term "red tide" is used to describe a bloom of harmful algal species called Karenia brevis, which can cause respiratory problems in humans and animals.
In 2001, the harmful algal bloom killed thousands of fish and had an impact on the shell fishing industry in a number of the state's bays, according to NASA.
"Red tides can have significant environmental impacts and threaten the health of some people," said Richard Edwing, director of NOAA's Center for Operational Oceanographic Products and Services.
Respiratory irritation in humans can occur when an algal bloom of the red tide organism is present along the coast and winds blow the aerosol it produces on shore, according to the National Weather Service.
Symptoms associated with a red tide are typically temporary and can include coughing, sneezing, and itching and tearing eyes. Symptoms may be worse in those who suffer from asthma, emphysema or other chronic respiratory disorders.
Red tides can also be harmful to marine life. Reports of dead fish have already been received from Charlotte County, Fla.
The red tide beach hazard is in effect for Sarasota, Charlotte, Northern Lee, Central and Southern Lee Counties, according to the NWS Service.
NOAA Respiratory Impact Forecast by County:
Sarasota County: Alongshore/Gulf side and in the Bay Regions patchy moderate respiratory impacts are possible through Thursday.
Charlotte County and Northern Lee County: Alongshore/Gulfside patchy moderate respiratory impacts are possible through Thursday. In bay regions, patchy high respiratory impacts possible through Thursday.
Central and Southern Lee County: Alonshore/Gulfside patchy moderate respiratory impacts are possible through Thursday.
Another visit from the Polar Vortex will deliver unseasonably cool air to the Midwest, preceded by rounds of thunderstorms, including severe weather.
The hot weather seen across the Northwest over the weekend will carry over into the new week, continuing the risk of heat-related illness.
Friday night saw two breathtaking phenomoma light up the sky, Manhattanhenge and the Supermoon.
Starting on Sunday, the Northeast and mid-Atlantic will be faced with severe thunderstorms and flooding downpours on multiple days before the new week ends on a more refreshing note.
Parts of the South will get major relief from heat, humidity and storms next week while other locations will be at greater risk for flash flooding.
