NWS: Urgent message - high heat index until 8pm
June 20, 2024 738 am EDT
Urgent weather message issued 340 am June 20 from National Weather Service forecast center in Binghamton
HEAT ADVISORY REMAINS IN EFFECT UNTIL 8 PM EDT THURSDAY...Heat index values up to 95 to 100 degrees until 8 PM EDT this evening. Slightly cooler temperatures are expected on Friday for portions of Central New York.
Hot temperatures and high humidity may cause heat illnesses to occur. Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors. Young children and pets should never be left unattended in vehicles under any circumstances.

Current Streamflow Situation
An increase in streamflows on Genesee River and tributaries overnight, two stations rated above 90th percentile Thursday. The dry area of NYS continues with lower flow levels, five stations reporting extreme low Thursday. Mohawk River comes on the drought map overnight, below normal. The Lake Ontario minor tributaries west section remains at moderate drought as yesterday. Niagara River - Lake Erie watershed at north Chautauqua County remains below normal with HAB reports confirmed in Chautauqua Lake. Hudson River watershed runs below normal another day. St Lawrence watershed's Raquette River channel is clear of the drought map Thursday, however a first percentile flow on Raquette River at South Colton will likely bring this area back in a day. 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-six streamflow gauges placed in reference locations throughout the USA record flows above flood stage today. This is an decrease from twenty-seven 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: REgion 7 Amite River breached flood stage Wednesday afternoon running three inches over the channel at Hwy 22 near Maurepas. Coastal flooding Vermilion Bay ended yesterday afternoon, just spiking up again and appears to be flooding again, not yet registering as a flood on the USGS dashboard. More to follow. Ongoing since June 4, Region 1 watershed's Bayou Bodcau Lake is down overnight near Shreveport, currently recorded two feet over the basin. In Region 4, west boundary river Sabine water level has come down a few inches overnight, still more than a foot over near Logansport. Downstream near Ruliff the water level is down again, less than a foot out of the channel at 19000 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.
