Powerful Alaska Storm Ties Strongest on Record
A
potent storm approaching western Alaska this weekend has tied the
strongest recorded storm to impact the region.
13
December, 2015
This
storm comes a little over a year after ex-Super Typhoon Nuri
became the
most powerful system on record to
cross Dutch Harbor, Alaska, which is located in the Aleutian Islands,
with a central low pressure of 924 millibars (27.29 inches of Hg).
The
intensity of a storm is measured by the central pressure, with lower
pressure equating to a stronger system.
Previous
to Nuri, the old record stood at 925 millibars (27.32 inches of Hg)
at Dutch Harbor, Alaska, from a strong storm that hit on Oct. 25,
1977.
To
put this in perspective, Hurricane Katrina made landfall at 920
millibars (27.17 inches of Hg).
This
storm raced to the northeast and pounded the western Aleutian Islands
with hurricane-force winds on Saturday evening, rapidly intensifying
in the process.

Winds
have gusted to 122 mph (196 km/h) at Adak Island, Alaska, on Saturday
night.
Further
strengthening is forecast to occur once the storm enters the Bering
Sea, potentially breaking the intensity reached by ex-Super Typhoon
Nuri in November of 2014.

The
Aleutian Islands and west coast of Alaska will continue to experience
impacts regardless of whether the storm breaks the record strength.
Hurricane-force
winds, which are sustained winds or gusts of 74 mph or greater, will
howl across the western Aleutian Islands through Sunday. Gusts of
30-50 mph can be expected across the western Alaska coast on Sunday
through Monday.
Large
waves upwards of 40 feet should be anticipated, making it hazardous
to navigate the waters of the Bering Sea.
Waves
are not expected to be nearly as high along the west coast of Alaska,
but they could be high enough to cause coastal flooding and erosion.
Accumulating snow is also likely across this area.
Wind
and waves will lessen early next week as the storm weakens off the
coast of eastern Russia.
