...FLASH FLOOD WATCH IN EFFECT FROM NOON EDT TODAY THROUGH THIS
EVENING...

The National Weather Service in Upton has issued a

* Flash Flood Watch for portions of southern Connecticut,
  northeast New Jersey, and southeast New York, including the
  following areas, in southern Connecticut, Northern Fairfield,
  Northern Middlesex, Northern New Haven, Southern Fairfield,
  and Southern 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 Nassau, Northern Queens, Northern
  Westchester, Richmond (Staten Island), Rockland, Southern
  Nassau, Southern Queens, and Southern Westchester.

* From noon EDT today through this evening

* A slow moving frontal system will bring numerous showers and
  thunderstorms to the region this afternoon into this evening.

* Any thunderstorms will have the potential to bring torrential
  downpours with rainfall rates of 1 to 2 inches per hour. These
  types of rainfall rates will cause urban and poor drainage
  flooding, with potential for flash flooding in areas affected by
  multiple successive thunderstorms. Additionally, rapid water
  level rises can occur on flashy small rivers and streams in
  basins affected by this activity.

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.

Thanks, Max.  You helped me pack my umbrella and rainboots today before I left for work.

Yes, thank you Max for saving me from dragging the hose and sprinkler around the yard to water our flowers! 

Thanks, Max. Safe home, everyone.

Max,

I have a flight out of Newark at 4:15 this afternoon. What flight delays are you projecting at this time?  Secondly, what impact do you think these projected delays will have on the length of TSA screening lines in C Terminal?

Raining heavily now in Maplecrest.
