[CTSARA] ...Flash Flood Watch in effect

[John Sabini Jr.]

...Flash Flood Watch in effect from late Tuesday night through
Wednesday afternoon...

The National Weather Service in New York has issued a

* Flash Flood Watch for all of southern Connecticut...northeast
 New Jersey and southeast New York...

* from late Tuesday night through Wednesday afternoon. 

* As a low pressure system over the Ohio Valley moves into the
 Great Lakes tonight into Tuesday...an onshore flow of deep
 tropical moisture will develop...and showers will gradually
 spread eastward into the region from Tuesday into Tuesday
 evening. This moisture will be wrung out by an upslope flow over
 interior sections...and also by a secondary low developing near
 the area late Tuesday night...and then moving slowly across
 during the day on Wednesday. 

* Showers will likely become heavy at times from late Tuesday
 night into Wednesday morning or early Wednesday afternoon.
 Rainfall rates of 1 to 2 inches per hour are likely during the
 periods of heaviest rain...and widespread rainfall amounts of 2
 to 3 inches and locally over 4 inches are possible. 

* Rainfall of this intensity and magnitude could cause significant
 urban and poor drainage flooding...that could impact the
 Wednesday morning rush. Flooding of small streams is also
 possible. The heavy rain could also combine with high water
 levels along the coast to exacerbate flooding problems in low
 lying coastal sections.

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.

351 PM EDT Mon Aug 11 2014

* locations...western Long Island Sound from northwestern 
 Suffolk County to New Haven County.

* Tidal departures...around a half a foot above astronomical 
 tides.

* Timing...tonight...mainly around the time of high tide.

* Impacts...minor coastal flood thresholds will be reached at a 
 few of the lowest lying locations along the shores of western 
 Long Island Sound. This will result in minor inundation of 
 only these most vulnerable spots.

* Outlook...more widespread minor coastal flooding is likely
 with the Tuesday morning and night high tide cycles...especially
 Tuesday night in combination with on going heavy rainfall.
