SITUATION OVERVIEW

------------------

Tropical Storm Isaias is expected to move through New England late

Tuesday into Wednesday. 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

-----------------

* FLOODING RAIN:

Prepare for dangerous rainfall flooding having possible significant

impacts across the higher terrain of NH and western ME. 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.

Prepare for locally hazardous rainfall flooding having possible

limited impacts across the rest of the region.

* WIND:

Prepare for hazardous wind having possible limited impacts across NEW

HAMPSHIRE AND WESTERN MAINE. Potential 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.

* TORNADOES:

Little to no impacts are anticipated at this time

across NEW HAMPSHIRE AND WESTERN MAINE.

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.
