...FLOOD WATCH REMAINS IN EFFECT UNTIL MIDNIGHT EDT TONIGHT...

* WHAT...Flash Flooding caused by slow moving thunderstorms and

  are possible.

* WHERE...Portions of central, northern, and southern New Hampshire,
  including the following areas, in New Hampshire, Western And
  Central Hillsborough. In central New Hampshire, Belknap,

  Northern Carroll, Northern Grafton, Southern Carroll and Southern

* WHEN...Until midnight EDT tonight.

* IMPACTS...Excessive runoff may result in flooding of already

* ADDITIONAL DETAILS...
  - Repeating rounds of heavy rainfall could result in localized

    of antecedent conditions.
