SIX HOURS From the Boston Harbor Association: Blizzard Junos storm surge peaks at low tide Fifth storm including Sandy to miss 100-year flood event by approximately six hours. According to preliminary data from NOAAs tide gauge, located in Boston Harbor just outside Fort Point Channel, Blizzard Junos peak storm surge of 4.74 feet reached Bostons waterfront at low tide, just after 11 am today. Click here to see data. Even so, this mornings coastal flood event of 3.37 feet above high tide that took place just after 4:30 am was the third-highest recorded in Boston in the last five years (tide gauge analysis courtesy Stephanie Kruel, VHB) Had Junos storm surge peaked during this mornings 4:30 high tide, Boston would have experienced a 100-year flood event of high tide plus five feet (MHHW+ 5). This is the fifth near miss in less than 2 1/2 years for Boston, including: Superstorm Sandy (October 29, 2012) Blizzard Nemo (February 9, 2013), Nor’easter Saturn (March 8, 2013) and Nor’easter Hercules (January 3, 2014). Had any of these five storms peaked at high tide instead of at low tide, flooding in Boston would have extended to the area on the map below. People living and working within these areas that flood at five feet above todays high tide need to identify and decrease their risks of flood damage. For existing structures, this involves temporarily or permanently sealing or raising at- or below grade openings such as windows, doors or grates and moving vehicles to higher ground.
