HAPPENING NOW
Lower Hudson River flooding
NWS: Coastal flood advisory -flash flooding possible this morning
Water news for Thursday, April 4, 2024 638 am EDT
National Weather Serivce Hazardous Weather Outlook issued 414 am April 4
COASTAL FLOOD ADVISORY IN EFFECT UNTIL 7 AM EDT THIS MORNING
This Hazardous Weather Outlook is for northeast New Jersey and
southeast New York. WHAT...1 to locally 2 ft of inundation above ground level expected in vulnerable areas near the waterfront and shoreline.
Minor to locally moderate flooding is expected in the most vulnerable locations near the waterfront and shoreline. Expect around 1 to locally 2 feet of inundation above ground
level in low lying, vulnerable areas. Some roads and low lying property including parking lots, parks, lawns and homes/businesses with basements near the waterfront will experience shallow flooding. The combination of heavy rain, runoff and elevated water levels Wednesday afternoon and overnight may cause localized flash flooding along some shoreline roads and properties. The coverage and magnitude of flooding late tonight will be dependent on track of low pressure, and timing of windshift from easterly gales to northwest gales. To account for this forecast uncertainty, a slight upward safety margin has been applied to the forecast water levels.
If travel is required, allow extra time as some roads may be closed. Do not drive around barricades or through water of unknown depth. Take the necessary actions to protect flood-prone
property.
Impacting New York (Manhattan)-Bronx-Richmond (Staten Island)-Kings(Brooklyn) in NYS and Hudson-Eastern Essex-Eastern Union Counties of New Jersey
Flood Tracker provisional data from USGS streamflow monitors
One hundred and forty-six streamflow gauges record flooding in the USA Thursday, up from one hundred and forty-three last night. WT tracks the nation's most common natural disaster dynamics through New York, Ohio, Georgia and Louisiana. As of this report we are watching 47 monitors indicating active flooding; 7 in New York, 5 in Georgia, 4 in Louisiana and 31 in Ohio.
New York State: Hudson River is flooding at Poughkeepsie and Piermont, Peconic River is flooding at Riverhead, Great South Bay is flooding at Lindenhurst, Shinnecock Bay is flooding at Ponquogue, Orient Bay is flooding at Orient. Ramapo River watershed and Long Island flows are running high or flooding, more to follow.
Current streamflow map for Ohio registers thirty-one monitored floodings through Wednesday night to Thursday morning, down from thirty five yesterday. Great Miami River, Mad River, Muskingum River, Scioto River, Licking River are flooding on, updates in progress with more to follow.
In Louisiana, Calcasieu River is still flooding in Region 4, near Glenmora. In Region 1 northwest LA, Bayou Bodcau is flooding near Shreveport. Pearl River is still in flood stage near Bogalusa in Washington Parish, still flooding downstream Town of Pearl River in St. Tammany Parish.
Georgia, Day 29: Gulf of Mexico side of the divide, Flint River is flooding at Lovejoy. On the Atlantic side of the drainage divide, Altamaha River is still flooding near Baxley. Savannah River still over near Cylo. Little Satilla and Satilla Rivers are flooding near Offerman and at Atkinson, respectively.
See black tags on the map for active flood, blue for high flow, 99th percentile or more.
As many NYS 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. WTNY.us tracks streamflow trends with an eye to the impacts on drinking water supply and quality in each of the state's 17 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.
