SITUATION OVERVIEW
------------------
Tropical Storm Isaias is expected to move through New England late Tuesday and Tuesday night. Heavy rainfall will be the primary threat but tropical storm force gusts are also possible. Areal and river flooding along with downed limbs and power outages will be possible.
POTENTIAL IMPACTS
-----------------
* WIND:
Prepare for dangerous wind having possible significant impacts across
western Maine and New Hampshire. Potential impacts in this area include:
- 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 are damaged, especially if unanchored. Unsecured
lightweight objects become dangerous projectiles.
- Numerous large trees snapped or uprooted, leading to downed
power lines.
- Many roads are impassable from debris, caused by downed trees
and power lines. Many bridges, causeways, and access routes
impassable.
- Numerous power and communications outages likely.
* SURGE:
Prepare for locally hazardous surge having possible limited impacts across coastal Maine and New Hampshire. Potential impacts in this area include:
- Splash-over near the time of high tide Tuesday night.
- Minor to moderate beach erosion. Heavy surf also breaching
dunes, mainly in usually vulnerable locations. Strong rip
currents.
- Minor coastal flooding due to inundation possible.
* FLOODING RAIN:
Prepare for dangerous rainfall flooding having possible significant
impacts across western Maine and New Hampshire. Potential impacts
include:
- Moderate rainfall flooding may prompt several evacuations and
rescues.
- Rivers and tributaries may quickly become swollen with swifter
currents and overspill their banks in a few places, especially
in usually vulnerable spots. Small streams, creeks, canals, and
ditches will 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
will become hazardous. Some road and bridge closures.
* TORNADOES:
An isolated tornado is possible across NEW HAMPSHIRE AND WESTERN MAINE.
* OTHER COASTAL HAZARDS:
Strong rip currents are possible.
PRECAUTIONARY/PREPAREDNESS ACTIONS
----------------------------------
* EVACUATIONS:
WATCH/WARNING PHASE - Listen to local officials for recommended
preparedness actions, including possible evacuation.
* OTHER PREPAREDNESS INFORMATION:
Now is the time to check your emergency plan and take necessary
actions to secure your home or business. Deliberate efforts should be
underway to protect life and property. Ensure that your Emergency
Supplies Kit is stocked and ready.
When making safety and preparedness decisions, do not focus on the
exact forecast track as there are inherent forecast uncertainties
which must be taken into account.
If you live in a place that is particularly vulnerable to high wind, such as a mobile home, an upper floor of a high rise building, or on a boat, plan to move to safe shelter. Take enough supplies for you
and your family for several days.
If you live in a place particularly vulnerable to flooding, such as near the ocean or a large inland lake, in a low lying or poor drainage area, in a valley or canyon, or near an already swollen
river, plan to move to safe shelter on higher ground
Always heed the advice of local officials and comply with any orders
that are issued. Do not needlessly jeopardize your life or the lives of others. When securing your property, outside preparations should be conducted as soon as possible before conditions deteriorate. The onset of strong gusty winds and heavy rain can cause certain preparedness
activities to become unsafe.
Be sure to let friends and other family members know of your
intentions and whereabouts for surviving the storm. For emergency
purposes, have someone located away from the threatened area serve as
your point of contact. Share vital contact information with others.
Keep cell phones handy and well charged.
Be a Good Samaritan and check on those who may not be fully aware of
the situation or who are unable to make personal preparations.
Visitors to the area should become familiar with nearby surroundings. If you are a visitor, know the name of the county or parish in which you are located and where it is relative to current watches and
warnings. If staying at a hotel, ask the management staff about their onsite disaster plan. Listen for evacuation orders, especially pertaining to area visitors.
Closely monitor NOAA Weather Radio or other local news outlets for
official storm information. Listen for possible changes to the
forecast.
