![]() ![]() Around this time, a NOAA analysis of Copernicus Sentinel-3 satellite data indicated that algae blooms covered about 380 square miles of the lake. Swirls and tendrils of blue-green algae can be seen in this image, acquired on June 12, 2023, by the Operational Land Imager-2 (OLI-2) on Landsat 9. The algae bloom led to the closure of parts of a marina and health warnings in neighboring counties. For a detailed explanation of features, view the Gulf of Mexico HAB Forecast Guide.Algae has covered about half of Lake Okeechobee-Florida’s largest freshwater lake-for much of June and early July 2023. Email notifications will be sent to subscribers when a bloom forms, weekly during a bloom, and when bloom conditions change. In addition to visiting the new website, you can subscribe to Gulf of Mexico forecasts to receive alerts and updates. It gives current red tide status and links to additional maps and graphics. brevis cells provided by the Florida Fish and Wildlife Conservation Commission monitoring program, from water samples over the last 8 days. State of Florida Observations show the concentration of K. The Beach Conditions Reporting System at Mote Marine Lab provides up to twice daily reports of various conditions at the beach, including respiratory irritation, visible dead fish, surf conditions, and more. brevis cells in seawater samples provided by several sources to help confirm blooms.įor the state of Florida, the new website includes additional partner resources. Colored circles overlaid on the satellite imagery indicate concentrations of K. Real-time Satellite Imagery: Shows bloom location and extent using images from the Copernicus Sentinel-3 Ocean and Land Colour Instrument (OLCI).Offshore winds and upwelling are responsible for bloom formation and intensification at the coast when the bloom begins. It is based on modeled oceanographic conditions. Intensification Forecast: Shows the likelihood that a bloom will develop or change and displays animated coastal bloom initiation and intensification.It is updated every three hours with any new information and is supported by volunteer citizen scientists equipped with the HABScope tool. Respiratory Irritation Forecast: Provides an estimate of the risk of respiratory irritation at individual beaches over the next 30 hours.The interactive dashboard from the National Centers for Coastal Ocean Science displays the following products: Analysis of "red tide" algal bloom locations and reported impacts are now automated, and reports include forecasts of potential development, intensification, transport, and impacts of algal blooms. The forecasts are higher resolution, providing hourly observations at the individual beach level. NOAA’s newly enhanced HAB forecasts are now available to the public in real time. Visit our harmful algal bloom portal for regional information, links, and resources. Forecasts also help beachgoers identify where and when coastal areas may be temporarily affected by a bloom. ![]() NOAA issues HAB forecasts to support the decisions of coastal resource managers, public health officials, and research scientists. Toxins can also accumulate in shellfish tissue and often lead to shellfish bed closures. In humans, red tide can lead to respiratory illness and eye irritation. These blooms can produce toxic chemicals that affect both marine organisms and humans, creating the potential to kill marine life. In the Gulf of Mexico, some harmful algal blooms (HABs) are caused by the microscopic algae species Karenia brevis, commonly called red tide. ![]()
