URGENT weather message from NMS: Heat stroke is an emergency
June 17, 2024 updated 432 pm EDT
URGENT weather message issued 1104 am June 17 by NWS Cleveland forecast center
HEAT ADVISORY REMAINS IN EFFECT UNTIL 8 PM EDT FRIDAY...Heat index values of 100 to 104 degrees are expected at times this week with variability each day due to clouds and scattered showers and storms, especially early in the week.
IMPACTS...Hot temperatures and high humidity may cause heat illnesses. Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors. Take extra precautions when outside. Wear lightweight and loose fitting clothing. Try to limit strenuous activities to early morning or evening. Take action when you see symptoms of heat exhaustion and heat stroke.
To reduce risk during outdoor work, the Occupational Safety and Health Administration recommends scheduling frequent rest breaks in shaded or air conditioned environments. Anyone overcome by heat should be moved to a cool and shaded location.
Heat stroke is an emergency! Call 9 1 1.

HABS Tracker satellite monitoring by the National Centers for Coastal Ocean Science (NCCOS)
A new sat image for Lake Erie captured June 16 at 8.1 mph shows Sandusky Bay HAB filling the inner and outer bay area with the highest concentrtion 1.5 million cells per 100 ml at the north edge and the south edge of the bloom mass in the inner bay and another area of high concentration in the outer bay area near the north shore beach off East Bayshore Rd, up to 1.5 million cells per 100 ml. Raw water intakes for Sandusky City and Upper Sandusky are located in the outer bay area with an alternate intake in Lake Erie. Routine testing is underway, total microcystins to June 8 showed below minimum reporting level. More to follow as new water testing results become available.

Streamflow Situation
from the USGS network of streamflow gauges in Ohio
The trend to lower streamflows continues Monday with below and much below normal ratings taking over the Ohio river monitors. The highest flows in the state as reported yesterday are found in Mahoning River watershed, these are still recording in the higher range of seasonal normal while most other normal ratings are tending toward the lower end of the range. The lowest flow recorded Monday is as reported the last few days, a 3rd percentile flow is still registering on the Cuyahoga River near Lake Erie. The drought map has expanded both in area and in drought severity overnight. Moderate drought rating is applied to Ashtabula-Chagrin watershed in the Lake Erie basin, adjacent Grand River watershed maintains the below normal rating added yesterday. New to the drought map Monday, Lower Great Miami watershed joins adjacent Scioto basin Paint River watershed at below normal. St. Mary's watershed has joined adjacent Upper Wabash in the Lake Erie basin at below normal, along with St. Josephs River and the Lower Maumee River watershed, all below normal. In the Muskingum River basin, Wills Creek has stepped back from moderate drought rating applied yesterday while Hocking River watershed appears with below normal rating. Ohio River minor tributaries still below normal include Little Beaver Creek, Wheeling, Shade, Raccoon-Symmes and Laughery watersheds.
WT USA Flood Tracker provisional data from the network of USGS streamflow monitors
Twenty-three streamflow gauges record flows above flood stage in the US Monday, down from thirty yesterday. WT USA follows the water levels and volume on three of these reference flood events, all occurring in the state of Louisiana.
Louisiana: West state border Sabine River flooding near Bon Wier ended yesterday afternoon. Upstream near Logansport the flow is up overnight, currently recorded a foot and four inches over minor flood stage at increased flow volume, from 23000 to now flowing over 26000 cubic feet per second. Near Ruliff the Sabine River a foot and nine inches above the channel flowing 33 thousand cubic feet per second. Region 1 Bayou Bodcau Lake continues to recede, down five inches overnight, currently recorded three feet and an inch above the basin near Shreveport. For more info on the flooding in Louisiana, see black tags indicating flood flow volume and gauge height updated daily here.
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.
