HEAT ADVISORY REMAINS IN EFFECT UNTIL 8 PM EDT THURSDAY...Heat index values of 100 to 104 expected in a portion of central New York. 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.

Current Streamflow Situation
A combination of normal and much below normal flows Wednesday with the concentration of much below normal ratings found through the northwest, and through the central and southeast drainage basins, including the Hudson River, Mohawk and Delaware and Ramapo River watersheds. The highest flow today is a single incidence of 90th percentile much above normal rating found in the Black River watershed. Seasonal normal is otherwise the highest rating found on the NYS dashboard. Extreme low flows are back on Ramapo River and Swan Rivers, 1st percentile water levels. The drought map has claimed the entire Hudson River watershed at below normal, the Lake Ontario minor tributaries west section has escalated to moderate drought overnight. A small area of the Niagara River - Lake Erie watershed at north Chautauqua County remains below normal as several HABs have been reported and confirmed on Chautauqua Lake. The south portion of Lake Champlain watershed in southeast Essex and north Washington is still below normal. St Lawrence watershed's Raquette River channel remains below normal through St. Lawrence County. As of this report, there are no floods observed in the NYS network of streamflow monitors and no extreme high flows.
From The Sensors provisional data on river flooding from the network of USGS streamflow monitors
Twenty-seven streamflow gauges placed in reference locations throughout the USA record flows above flood stage today. This is an increase from twenty-three yesterday. WT USA tracks the flow levels on four of these reference flood events, as the sensors read it, all occurring in the state of Louisiana.
Louisiana: Coastal flooding Vermilion Bay got above flood stage around 6 am this morning near Cypremort Point currently recorded three inches above flood stage and rising. Ongoing since June 4, Region 1 watershed's Bayou Bodcau Lake continues to flood the basin near Shreveport in Region 1, down six inches overnight and currently recorded at two feet and four inches above minor flood stage. In Region 4, west boundary river Sabine water level has peaked and started to recede near Logansport, currently recorded a foot and seven inches over minor flood stage. Flow volume has slowed for the first time in days, from over 27000 cubic feet per second yesterday to 26000 this morning. Downstream near Ruliff the water level is down three inches over the last twenty four hours, Sabine River currently running a foot and one inch over the channel, flow volume has dropped overnight from 27000 to 22000 cubic feet per second. 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.
