Intense, onshore winds will produce moderate to locally major coastal flooding around high tides Saturday morning. Flooding was reported in Weymouth, Mass., at the time of high tide Friday evening.

The areas at greatest risk are north and east-facing shorelines from Boston south into Cape Cod Bay, with tides 3-4' above normal already observed and expected to continue through Saturday morning's high tide!  

According to Michael Lowry, Hurricane Specialist and Storm Surge Expert at The Weather Channel (On Twitter), here are top five storm tide values at the Boston Harbor gauge in the historical record:

  • "Blizzard of '78" (Feb. 6, 1978):  4.82 feet
  • January 2, 1987:  3.92 feet
  • "Perfect Storm" (Oct. 30, 1991):  3.86 feet
  • January 28, 1979:  3.76 feet
  • 1992 Nor'easter (Dec. 12, 1992):  3.75 feet
  • All values are referenced to mean higher high water, i.e., the normal high tide level.

Lowry says a model storm surge forecast for Boston Harbor suggests this storm may produce a peak surge on par with both the 1992 Nor'easter and the January 1979 event, with the greatest threat during Saturday morning's high tide.

Tide levels at Boston were 4.21 feet above normal just after midnight Saturday morning.

Suffice to say, significant beach erosion will occur along the entire Mass. coast.  This may include some structural damage, flooding of basements along with numerous roads closed!  Those conditions were observed with Friday's evening high tide.

Significant coastal flooding is also expected Saturday morning along the sound side of Long Island and the "eastern forks", as well as parts of coastal Connecticut and the southern coast of Maine.  Minor to locally moderate coastal flooding is also expected along the Jersey shore and the Delmarva Peninsula.

Major impacts to interstate and air travel are forecasted with this storm. Be sure to check back with us at weather.com and The Weather Channel for the latest on this winter storm.

More Water For California: New Enormous Water Works Programs Are Expensive

By Dr. Jeff Masters
April 18, 2014

From November 2013 - January 2014, a remarkably extreme jet stream pattern set up over North America, bringing the infamous "Polar Vortex" of cold air to the Midwest and Eastern U.S., and a "Ridiculously Resilient Ridge" of high pressure over California, which brought the worst winter drought conditions ever recorded to that state. A new study by Utah State scientist S.-Y. Simon Wang found that this jet stream pattern was the most extreme on record, and likely could not have grown so extreme without the influence of human-caused global warming.

A Warm Winter in Alaska

In contrast to much of the contiguous U.S., the National Weather Service (NWS) in Alaska noted in a post this week that Alaska has enjoyed its third warmest ‘winter’ on record for 2013-2014. The period of time they are calling ‘winter’ is for the six months of October 2013 through 2014. Here are a few details.

What the 5th IPCC Assessment Doesn't Include

By Angela Fritz
September 27, 2013

Melting permafrost has the potential to release an additional 1.5 trillion tons of carbon into the atmosphere, and could increase our global average temperature by 1.5°F in addition to our day-to-day human emissions. However, this effect is not included in the IPCC report issued Friday morning, which means the estimates of how Earth's climate will change are likely on the conservative side.
