954 first-hand accounts of flood events in Massachusetts, ranked by impact. Each is a NOAA-written narrative of the moment.
High spring astronomical tides combined with low pressure off the east coast of Massachusetts to produce coastal flooding. This unseasonable coastal low pressure contributed to the flooding lasting through multiple tide cycles.

Read the full account →Low pressure moving up the east coast brought a soaking rain and strong winds to much of southern New England. The strongest winds were along the east coast of Massachusetts where many trees were still fully leaved.
Read the full account →Several areas of low pressure traveled along a stationary front stalled across Southern New England producing showers and a few thunderstorms. In addition, strong southerly flow brought in a very moist airmass with precipitable water values above two inches.
Read the full account →A warm front stalled along the northern Massachusetts border. Low pressure moved from the Mid Atlantic states up across Southeast Massachusetts during the night of the 18th and early morning of the 19th.
Read the full account →Low pressure tracking toward southern New England tapped into a plume of tropical moisture and produced torrential rainfall over parts of central and northeast Massachusetts in the matter of a few hours.

Read the full account →A cold front moved into New England the evening of August 7th and stalled just north of Massachusetts. The airmass over the state was very humid and unstable. This generated strong thunderstorms, some causing damage.
Read the full account →An historic winter storm deposited tremendous amounts of snow over all of southern New England, mainly from the mid-afternoon on Friday, February 8 and lasting into the daylight hours of Saturday, February 9.
Read the full account →An upper level disturbance moved over southern New England bringing showers and thunderstorms to the region. Precipitable water values over two inches indicated a very moist atmosphere; in addition, weak winds at the mid levels resulted in very slow moving storms.
Read the full account →A powerful storm system moving very slowly from the Ohio Valley to the eastern Great Lakes caused strong winds and heavy rainfall to Massachusetts, resulting in urban street flooding, basement flooding, small stream flooding, and main stem river flooding.
Read the full account →A stacked low pressure system passed south and east of southern New England bringing widespread rainfall to much of the region. This system was anomalously moist with precipitable waters two to three standard deviations above normal for late March.
Read the full account →Low pressure southeast of Nantucket produced widespread showers across southern New England. These showers trained over an area known as the North Shore in Massachusetts, including the towns of Peabody, Swampscott, and Salem.
Read the full account →An atmospheric trough moved over Massachusetts on the 4th, tapping high amounts of moisture in the air to cause heavy showers that resulted in flooding. Up to 6.5 inches of rain fell on Cape Cod, and 1 to 3 inches across the rest of Massachusetts.
