NWS: Potential for tornado, localized flooding in Lake Erie drainage basin
June 29, 2024 updated 944 am EDT
Hazardous Weather Outlook issued by National Weather service Cleveland 350 am EDT Saturday June 29
Showers and thunderstorms are expected today, some of which could
become severe. The primary weather hazard will be damaging winds,
though a tornado or two and some hail will be possible. Heavy
rainfall could also lead to localized flooding.

HAB Tracker satellite monitoring program of the NOAA National Centers for Coastal Ocean Science
WT follows the movement and growth of harmful algal blooms (HABs) as provided by the satellite monitoring program of the NCCOS for New York's Lake Champlain, Ohio's Lake Erie and Louisiana's Lake Pontchartrain and surrounding area. Interpretation of satellite images is best in clear conditions at wind speed less than 4 pm, where the appearance and extent of HABs is reliably matched to a color scale for concentration. HABs are known to produce algal toxins of concern for raw drinking water sources and recreational water bodies.
New York
Lake Champlain widespread HAB off the northeast shore on the Canadian side of the border has accelerated in concentration from the initial sighting around 400 thousand cells per 100 ml on June 26. The latest image was captured June 28, shows the widespread HAB in Baie Missisquoi matching the color scale at extreme high concentration, 1 million to 2 million cells per 100 ml. The highest concentration appears on the east side of the bloom mass. Two additional HAB reports for Lake Champlain have been confirmed by NYS Department of Environmental Conservation, both found off the west shore at Point au Roche in Clinton County in the bays between Short Point and Long Point. Plan beach access to avoid HABs and consider carrying a rapid test kit for microcystins. Forty-five HABs were posted on the active notifications for NYS Friday afternoon, the latest NYS HAB report is here.
Louisiana: Southeast LA water bodies are captured in a wide angle pass by the Copernicus-Sentinel III satellite, catching Lake Pontchartrain to Black Bay in frame. The latest image was captured June 28 at a surface wind speed 6.3 mph. Lake Pontchartrain HAB is not visible in this capture as reported from the June 27 image. This latest image is mostly cloud obscured, we refer to the June 27 image showing Lake Pontchartrain HAB off the north shore Big Branch Marsh, also Lakes Verret, Palourde, Boeuf widespread HABs around 700 to 800 thousand cells per 100 ml, Lac des Allemands, Bayou Fortier widespread HABs in the range of 400 thousand cells per 100 ml. The latest HAB report for Louisiana is available here.
Ohio: Lake Erie west basin is captured by the NCCOS monitoring satellite, the latest upload taken June 28 at wind speed 13.8 mph. The image is cloud obscured in the west with no view of Maumee Bay, clear in the east with "Sandy" the Sandusky Bay HAB completely visible, maintaining the high concentration and filling inner and outer bay area up to 2 million cells per 100 ml in the inner bay closer to the mainland. Sandy appeared in Sandusky Bay on June 11, since expanding to fill the inner and outer bay areas and accelerating in concentration to extreme levels not seen at this time of year, nor in this location in 2023. The full Ohio HAB report is available here.
Drinking Water Advisories
Putnam: Continental Village has been placed under a system-wide BWA, according to Putnam County Sheriff's office, a water line break occurred Wednesday in the south side area prompting the boil order. Continental Village public water facility supplies potable water to 1153 residential customers from a groundwater source.
As many drinking water facilities are supplied from surface water reservoirs, the streamflow situation is pertinent to both drinking water supply and quality. High flows can stir up sediment and cause turbidity in the reservoirs, requiring additional treatments to render the water potable. Low flow volume is linked to warmer temperatures in the reservoir and can be an issue for water quality where HABs are present. WT tracks streamflow trends with an eye to the impacts on drinking water supply and quality in each of the state's watersheds. Check the watershed layer on the map to see the direction of flow and streamflows that may be impacting drinking water today.
USGS Provisional Data Statement
Data are provisional and subject to revision until they have been thoroughly reviewed and received final approval. Current condition data relayed by satellite or other telemetry are automatically screened to not display improbable values until they can be verified.
Provisional data may be inaccurate due to instrument malfunctions or physical changes at the measurement site. Subsequent review based on field inspections and measurements may result in significant revisions to the data.
Data users are cautioned to consider carefully the provisional nature of the information before using it for decisions that concern personal or public safety or the conduct of business that involves substantial monetary or operational consequences. Information concerning the accuracy and appropriate uses of these data or concerning other hydrologic data may be obtained from the USGS.
