...TROPICAL STORM WATCH IN EFFECT...

A Tropical Storm Watch means tropical storm-force winds are possible
somewhere within this area within the next 48 hours

* LOCATIONS AFFECTED
    - Coney Island
    - Bay Ridge
    - Flatbush

* WIND
    - LATEST LOCAL FORECAST: Equivalent Tropical Storm force wind
        - Peak Wind Forecast: 35-45 mph with gusts to 60 mph
        - Window for Tropical Storm force winds: Tuesday afternoon
          until early Wednesday morning

    - THREAT TO LIFE AND PROPERTY THAT INCLUDES TYPICAL FORECAST
      UNCERTAINTY IN TRACK, SIZE AND INTENSITY: Potential for wind 58
      to 73 mph
        - PLAN: Plan for dangerous wind of equivalent strong tropical
          storm force.
        - PREPARE: Efforts to protect life and property should now be
          underway. Prepare for significant wind damage.
        - ACT: Act now to complete preparations before the wind
          becomes hazardous.

    - POTENTIAL IMPACTS: Significant
        - 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.

* STORM SURGE
    - LATEST LOCAL FORECAST: Localized storm surge possible
        - Peak Storm Surge Inundation: The potential for up to 2 feet
          above ground somewhere within surge prone areas
        - Window of concern: Tuesday afternoon until early Wednesday
          morning

    - THREAT TO LIFE AND PROPERTY THAT INCLUDES TYPICAL FORECAST
      UNCERTAINTY IN TRACK, SIZE AND INTENSITY: Potential for storm
      surge flooding greater than 1 foot above ground
        - PLAN: Plan for storm surge flooding greater than 1 foot
          above ground.
        - PREPARE: Efforts should now be underway to prepare for
          storm surge flooding, especially in low-lying vulnerable
          areas.
        - ACT: Take actions to protect life and property. Prepare to
          leave if evacuation orders are given for your area.

    - POTENTIAL IMPACTS: Limited
        - 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,
          mainly 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.

* FLOODING RAIN
    - LATEST LOCAL FORECAST: Flash Flood Watch is in effect
        - Peak Rainfall Amounts: Additional 2-4 inches, with locally
          higher amounts

    - THREAT TO LIFE AND PROPERTY THAT INCLUDES TYPICAL FORECAST
      UNCERTAINTY IN TRACK, SIZE AND INTENSITY: Potential for
      moderate flooding rain
        - PLAN: Emergency plans should include the potential for
          moderate flooding from heavy rain. Evacuations and rescues
          are possible.
        - PREPARE: Consider protective actions if you are in an area
          vulnerable to flooding.
        - ACT: Heed any flood watches and warnings. Failure to take
          action may result in serious injury or loss of life.

    - POTENTIAL IMPACTS: Significant
        - Moderate rainfall flooding may prompt several evacuations
          and rescues.
        - Rivers and streams may quickly become swollen with swifter
          currents and may overspill their banks in a few places,
          especially in usually vulnerable spots. Small streams,
          creeks, canals, and ditches may overflow.
        - Flood waters can enter some structures or weaken
          foundations. Several places may experience expanded areas
          of rapid inundation at underpasses, low lying spots, and
          poor drainage areas. Some streets and parking lots take on
          moving water as storm drains and retention ponds overflow.
          Driving conditions become hazardous. Some road and bridge
          closures.

* TORNADO
    - LATEST LOCAL FORECAST:
        - Situation is somewhat favorable for tornadoes

    - THREAT TO LIFE AND PROPERTY THAT INCLUDES TYPICAL FORECAST
      UNCERTAINTY IN TRACK, SIZE AND INTENSITY: Potential for a few
      tornadoes
        - PLAN: Emergency plans should include the potential for a
          few tornadoes.
        - PREPARE: If your shelter is particularly vulnerable to
          tornadoes, prepare to relocate to safe shelter before
          hazardous weather arrives.
        - ACT: If a tornado warning is issued, be ready to shelter
          quickly.

    - POTENTIAL IMPACTS: Limited
        - 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.

When was the last time 2 tropical  storms hit NYC in one summer ?

[weatherlogix]

Quick question....if you were to try to get to the beaches (Atlantic/Long Beach) on Tuesday to see the storm at its max, including high tides, what time of day would be best? Thanks in advance

I know 1960 had two that came up the coast...not sure if there have been more than one since...

[MJO812]

HWRF and HMON keeps the low west of the city

1955 Connie and Diane within about a week. Caused some of the worst flooding ever seen in parts of the northeast, especially Ct.

[MJO812]

18z Euro is slightly west and drier for NYC east.

The Delaware and Lehigh Valleys and the Poconos got slammed as well. Up to 20" of rain in parts of NEPA with Diane. The river flooding was historic but the flash flooding on the smaller tributaries was even worse.

Quite the summer with an incredibly hot and dry July and early August (with an impressive number of 95 degree days) followed by historically heavy rainfall.

What are we looking at worst case scenario if it stays East for NYC area .

Mainly the axis of heaviest rain and thus flooding shifting further east and overspreading most of the metro area. Winds would have less of an impact, save for eastern LI.

[MJO812]

Nam is slightly west

Heaviest rain west of NYC with bigger winds in Li

[MJO812]

Very strong winds for NYC east on the Nam with the low being west of NYC.

Hasn’t the storm been running east of it’s forecast track?

[MJO812]

Yes

[MJO812]

3k Nam barely has rain for the coast but alot of wind.

[HeadInTheClouds]

NHC still has storm going right over NYC. 

 

[larrye]

The way I see it, the NAM, GFS, GFS-Para, and HWRF all having the center just west of NYC with the Euro being the only one who has it NYC on east. At least as of now. I will stand corrected if someone with more modeling skills disagrees.

Euro and Ukie are similar

Yep, and the 00z GFS keeps it west of NYC.

[TriPol]

EURO hasn't been great with this storm, but it's much more east now than it used to be. So thinking it might skirt the Carolinas and head right up the coast alla Gloria.

It did shift slightly east with the heavy precip

[MJO812]

[Rtd208]

If the further west track on some of the models is correct then that would give areas in the immediate metro area less rainfall but put those areas in a better position for higher winds and maybe some severe weather including a few tornadoes. We will have to see how the PRE sets up later tomorrow and tomorrow night but I suspect that may be mostly north and west of the metro area. I would still expect 2-4" of rainfall in and around the city (especially the city on west) with locally higher amounts. Lets see how things develop.

Winds are really strong in our area

Gusts are over hurricane  status

Wow! Yeah the Jersey Shore and Long Island are gonna get clocked with winds. I’m surprised people are downplaying it. Nearly all the models show hurricane force gusts for the shore points... Care to share the ukie wind map?
