Hurricane Local Statement
Tropical Storm Isaias Local Statement Advisory, National Weather Service New York NY, 605 AM EDT, Tuesday, Aug 4 2020
This product covers Southeast New York, Northeast New Jersey, and Southern Connecticut
**ISAIAS IS MOVING NORTH OVER CENTRAL VIRGINIA**
NEW INFORMATION
CHANGES TO WATCHES AND WARNINGS: None
CURRENT WATCHES AND WARNINGS: A Tropical Storm Warning is in effect for Bronx, Eastern; Bergen, Eastern Essex, Eastern Passaic, Eastern Union, Hudson, Kings (Brooklyn), New York (Manhattan), Northeastern Suffolk, Northern Fairfield, Northern Middlesex, Northern Nassau, Northern New Haven, Northern New London, Northern Queens, Northern Westchester, Northwestern Suffolk, Orange, Putnam, Richmond (Staten Island), Rockland, Southeastern Suffolk, Southern Fairfield, Southern Middlesex, Southern Nassau, Southern New Haven, Southern New London, Southern Queens, Southern Westchester, Southwestern Suffolk, Western Bergen, Western Essex, Western Passaic, and Western Union.
STORM INFORMATION: About 360 miles south-southwest of New York City NY or about 450 miles southwest of Montauk Point NY 36.3N 77.5W; Storm Intensity 70 mph; Movement North-northeast or 20 degrees at 28 mph
SITUATION OVERVIEW:
Tropical Storm Isaias, located in inland Virginia, will continued to move to north-northeast this morning along the Mid-Atlantic coast. Isaias will slowly weaken as it accelerates northeast today, likely moving over our area this afternoon and evening. However, confidence continues to increase with respect to the magnitude of local hazards and impacts.
The main threats with this system involve heavy rainfall, strong winds, minor to moderate coastal flooding, along with high surf and dangerous rip currents. Additionally, a few tornadoes are possible.
Locally heavy rainfall is expected with a widespread 1 to 3 inches, with localized amounts up to 5 inches possible. The heaviest rain is most likely to occur across New York City, Northeast New Jersey and the Lower Hudson Valley this morning through this evening, and eastern sections this afternoon into tonight. The strongest winds are likely to occur across New York City Metro, Long Island, northeast New Jersey, southern portions of the Lower Hudson Valley, and southeast Connecticut.
Dangerous marine conditions are likely across all of the coastal waters today and tonight. High surf and dangerous rip currents are expected to continue along the ocean beaches today through Wednesday.
The effects from Tropical Storm Isaias are expected to diminish quickly from southwest to northeast across the area late tonight into Wednesday morning.
POTENTIAL IMPACTS
FLOODING RAIN: Protect against life-threatening rainfall flooding having possible extensive impacts across New Jersey, New York City, the Lower Hudson Valley, and portions of southeastern Connecticut. Potential impacts include:
– Major rainfall flooding may prompt many evacuations and rescues.
– Rivers and streams may rapidly overflow their banks in multiple places. Small streams, creeks, canals, and ditches may become dangerous rivers. Flood control systems and barriers may become stressed.
– In hilly terrain, destructive runoff may run quickly down valleys, and increase susceptibility to rockslides and mudslides.
– Flood waters can enter many structures within multiple communities, some structures becoming uninhabitable or washed away. Many places where flood waters may cover escape routes. Streets and parking lots become rivers of moving water with underpasses submerged. Driving conditions become dangerous. Many road and bridge closures with some weakened or washed out.
WIND: Protect against dangerous wind having possible significant impacts across Southeast New York, Northeast New Jersey, and Southern Connecticut. Potential impacts in this area include:
– Some damage to roofing and siding materials, along with damage to porches, awnings, carports, and sheds. A few buildings experiencing window, door, and garage door failures. Mobile homes damaged, especially if unanchored. Unsecured lightweight objects become dangerous projectiles.
– Several large trees snapped or uprooted, but with greater numbers in places where trees are shallow rooted. Several fences and roadway signs blown over.
– Some roads impassable from large debris, and more within urban or heavily wooded places. A few bridges, causeways, and access routes impassable.
– Scattered power and communications outages, but more prevalent in areas with above ground lines
SURGE: Protect against locally hazardous surge having possible limited impacts across shoreline communities. Potential impacts in this area include:
– Localized inundation with storm surge flooding mainly along immediate shorelines and in low lying spots, or in areas farther inland near where higher surge waters move ashore.
– Sections of near shore roads and parking lots become overspread with surge water. Driving conditions dangerous in places where surge water covers the road.
– Moderate beach erosion. Heavy surf also breaching dunes, mainl in usually vulnerable locations. Strong and frequent rip currents.
– Minor to locally moderate damage to marinas, docks, boardwalks, and piers. A few small craft broken away from moorings. Elsewhere across Southeast New York, Northeast New Jersey, and Southern Connecticut, little to no impact is anticipated.
TORNADOES: Protect against a tornado event having possible limited impacts across Southeast New York, Northeast New Jersey, and Southern Connecticut. Potential impacts include:
– The occurrence of isolated tornadoes can hinder the execution of emergency plans during tropical events.
– A few places may experience tornado damage, along with power and communications disruptions.
– Locations could realize roofs peeled off buildings, chimneys toppled, mobile homes pushed off foundations or overturned, large tree tops and branches snapped off, shallow rooted trees knocked over, moving vehicles blown off roads, and small boats pulled from moorings.
PRECAUTIONARY/PREPAREDNESS ACTIONS
Now is the time to check your emergency plan and emergency supplies kit and take necessary actions to protect your family and secure your home or business.
Keep cell phones well charged. Cell phone chargers for automobiles can be helpful, but be aware of your risk for deadly carbon monoxide poisoning if your car is left idling in a garage or other poorly ventilated area.
Rapidly rising flood waters are deadly. If you are in a flood prone area, consider moving to higher ground. Never drive through a flooded roadway. Remember, Turn Around Don`t Drown!
Storm surge is the leading killer associated with tropical storms and hurricanes! Make sure you are in a safe area away from the surge zone. Even if you are not in a surge prone area, you could find yourself cut off by flood waters during and after the storm. Heed evacuation orders issued by local authorities.
If in a place that is vulnerable to high winds, such as near large trees, a mobile home, upper floors of a high rise building, or on a boat, consider moving to a safer shelter before the onset of strong winds or flooding.
If a Tornado Warning is issued for your area, be ready to shelter quickly, preferably away from windows and in an interior room not prone to flooding. If driving, scan the roadside for quick shelter options.
Closely monitor http://weather.gov, NOAA Weather radio or local news outlets for official storm information. Be ready to adapt to possible changes to the forecast. Ensure you have multiple ways to receive weather warnings.

Flash Flood Watch
Flood Watch. National Weather Service New York NY, 433 AM EDT Tue Aug 4 2020
FLASH FLOODING POSSIBLE WITH TROPICAL STORM ISAIAS…Northern Fairfield-Northern New Haven-Western Passaic-Eastern Passaic-Hudson-Western Bergen-Eastern Bergen-Western Essex-Eastern Essex-Western Union-Eastern Union-Orange-Putnam-Rockland-Northern Westchester-Southern Westchester-New York (Manhattan)-Bronx-Richmond (Staten Island)-Kings (Brooklyn)-Northern Queens-Southern Queens-
FLASH FLOOD WATCH REMAINS IN EFFECT THROUGH LATE TONIGHT…
The Flash Flood Watch continues for portions of southern Connecticut, northeast New Jersey, and southeast New York, including the following areas, in southern Connecticut, Northern Fairfield and Northern New Haven.
In northeast New Jersey, Eastern Bergen, Eastern Essex, Eastern Passaic, Eastern Union, Hudson, Western Bergen, Western Essex, Western Passaic, and Western Union. In southeast New York Bronx, Kings (Brooklyn), New York (Manhattan), Northern Queens, Northern Westchester, Orange, Putnam, Richmond (Staten Island), Rockland, Southern Queens, and Southern Westchester.
Through late tonight; Tropical Storm Isaias will track through the area today.
A total of 1 to 3 inches of rain will be possible with locally higher amounts of up to 5 inches. Torrential downpours with multiple rounds of heavy showers will allow for excessive runoff and therefore would cause flash flooding in low lying, urban and poor drainage areas. Some rivers and streams across the path of the heavier rainfall axis could experience minor to moderate rises resulting in possible road closures and inundation of structures near the streams.
PRECAUTIONARY/PREPAREDNESS ACTIONS…
A Flash Flood Watch means that conditions may develop that lead to flash flooding. Flash flooding is a very dangerous situation.
You should monitor later forecasts and be prepared to take action should flash flood warnings be issued.
