SITUATION OVERVIEW
------------------

Isaias has become post-tropical and continues to gradually weaken
as it moves into Canada tonight. The next several hours may continue
to see occasional tropical storm conditions, but steady improvement is
expected overnight.

Tropical storm force gusts continue across the area, and especially
over the coastal waters. A few gusts to 40 or 50 mph remain possible,
which will be capable of downing some trees and power lines. The heavy
rainfall threat is also coming to an end, as rain bands continue to
move north.

The coastal flooding threat remains low based on the fact that the
storm has moved faster than previous forecasts and is not timing
favorably with high tide. Some splashover is expected during the high
tide tonight. Rough surf and an increased risk for dangerous rip
currents will be possible behind Isaias on Wednesday.

POTENTIAL IMPACTS
-----------------

* WIND:
Potential impacts from the main wind event are now unfolding across
New Hampshire and western Maine. Remain well sheltered from hazardous
wind having additional limited impacts. If realized, these impacts
include:
    - Damage to porches, awnings, carports, sheds, and unanchored
      mobile homes. Unsecured lightweight objects blown about.
    - Many large tree limbs broken off. A few trees snapped or
      uprooted, leading to downed power lines.
    - A few roads impassable from debris, caused by downed branches
      and power lines. Hazardous driving conditions on bridges and
      other elevated roadways.
    - Scattered power and communications outages likely.

* SURGE:
Little to no storm surge impacts are anticipated at this time across
New Hampshire and western Maine.

* FLOODING RAIN:
Potential impacts from the flooding rain are still unfolding across
the western Maine mountains. Remain well guarded against locally
hazardous flood waters having additional limited impacts. If realized,
these impacts include:
    - Localized rainfall flooding may prompt a few evacuations.
    - Rivers and tributaries may quickly rise with swifter currents.
      Small streams, creeks, canals, and ditches may become swollen
      and overflow in spots.
    - Flood waters can enter a few structures, especially in usually
      vulnerable spots. A few places where rapid ponding of water
      occurs at underpasses, low-lying spots, and poor drainage
      areas. Several storm drains and retention ponds become
      near-full and begin to overflow. Some brief road and bridge
      closures.

Elsewhere across NEW HAMPSHIRE AND WESTERN MAINE, little to no impact
is anticipated.

* TORNADOES:
Little to no additional impacts are anticipated at this time
across New Hampshire and western Maine.

PRECAUTIONARY/PREPAREDNESS ACTIONS
----------------------------------
Now is the time to remain safely sheltered from the storm. Stay
inside and away from windows. Listen for updates and be ready in case
you lose electrical power. Locate your battery powered radio and
flashlight from your Emergency Supplies Kit. Keep these items close.

Continue to keep your cell phone well charged for as long as
possible. If you lose power, use it more sparingly and mainly for
personal emergencies and check-ins. Do not overload communications
systems with idle chatter.

Do not be a thrill seeker or risk your life for senseless photos or
videos. Be wise and avoid becoming another statistic.

Be ready to move to the identified safe room if your home or shelter
begins to fail. Quickly move to an interior room on the lowest floor.
Put as many sturdy walls between you and the storm as you can.
Protect your head and body.
