SITUATION OVERVIEW
------------------
Isaias is expected to track quickly through western New England
Tuesday evening into the overnight. The majority of storm impacts will
be felt in roughly a 6 hour period Tuesday night.
Southerly winds are expected to increase in the early evening and gust
to 40 to 60 mph at times as Isaias tracks near the Connecticut River
Valley. This may be capable of downing some trees and power lines. In
addition, there will be a threat for isolated tornadoes on the eastern
side of Isaias. Winds will begin to diminish early Wednesday morning.
Rainfall totals of 1 to 3 inches are expected, mainly in the
Connecticut River Valley and White Mountains. This may lead to flash
flooding in complex terrain or poor drainage areas, in addition to
minor river flooding. Parts of the forecast area near the coast may
see less than 1 inch rainfall.
In general the coastal flood threat is low based on the speed of
Isaias, with any inundation likely less than a foot. Some splashover
is expected during the Tuesday night high tide however. Rough surf and
an increased risk for dangerous rip currents will be possible both
ahead of Isaias on Tuesday and behind it on Wednesday.
POTENTIAL IMPACTS
-----------------
* WIND:
Protect against 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.
* SURGE:
Little or no inundation flooding is expected, but splashover and beach
erosion is expected around the time of high tide Tuesday night.
* FLOODING RAIN:
Protect against dangerous rainfall flooding having possible
significant impacts across the Connecticut River Valley and White
Mountains into the western Maine mountains. 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.
Protect against locally hazardous rainfall flooding having possible
limited impacts across southern New Hampshire and coastal western
Maine.
* TORNADOES:
Protect against a tornado event having possible limited impacts
across southern and central New Hampshire and southwestern Maine.
Potential impacts include:
- The occurrence of isolated tornadoes can hinder the execution
of emergency plans during tropical events.
- A few places may experience tornado damage, along with power
and communications disruptions.
- Locations could realize roofs peeled off buildings, chimneys
toppled, mobile homes pushed off foundations or overturned,
large tree tops and branches snapped off, shallow-rooted trees
knocked over, moving vehicles blown off roads, and small boats
pulled from moorings.
PRECAUTIONARY/PREPAREDNESS ACTIONS
----------------------------------
* EVACUATIONS:
If evacuating away from the area or relocating to a nearby shelter,
leave early before weather conditions become hazardous. Listen to
local officials for recommended preparedness actions, including
possible evacuation.
* OTHER PREPAREDNESS INFORMATION:
Now is the time to bring to completion all preparations to protect
life and property in accordance with your emergency plan.
Outside preparations should be wrapped up as soon as possible before
weather conditions completely deteriorate.
Check-in with your emergency points of contact among family, friends,
and workmates. Inform them of your status and well-being. Let them
know how you intend to ride out the storm and when you plan to
check-in again.
Keep cell phones well charged and handy. Also, cell phone chargers
for automobiles can be helpful after the storm. Locate your chargers
and keep them with your cell phone.
In emergencies it is best to remain calm. Stay informed and focused
on the situation at hand. Exercise patience with those you encounter.
Be a Good Samaritan and helpful to others.
If relocating to a nearby shelter or to the home of a family member
or friend, drive with extra caution, especially on secondary roads.
Remember, many bridges and causeways will be closed once higher winds
arrive. Also, if you encounter water covering the road, seek an
alternate route. Always obey official road signs for closures and
detours.
If you are a visitor and still in the area, listen for the name of
the city or town in which you are staying within local news updates.
Be sure you know the name of the county or parish in which it
resides. Pay attention for instructions from local authorities.
Closely monitor NOAA Weather radio or other local news outlets for
official storm information. Be ready to adapt to possible changes to
the forecast.
