Flash Flood — Jan 13, 2024
The second severe storm in a week���s time struck the northern New England coastline during the middle of January. An intense and rapidly deepening area of low pressure over the Great Lakes region (979 mb) combined the highest astronomical tides of the month to produce extreme flooding along the coast.

Coastal Flood — Mar 10, 2024
High pressure in control on the 9th began to slide northeast through the day as primary low pressure moved through the Great Lakes into southern Canada. A secondary area of low pressure developed over inland areas of the Carolinas. Sustained warm air advection forced a large area of moderate to heavy precipitation up and over the colder near-surface air mass. Light precipitation began as a mix,...
Coastal Flood — Jan 10, 2024
A powerful storm tracked northeast through the Mid Mississippi River Valley on the 9th, rapidly deepening as it approached the southern Great Lakes. Precipitation formed along and ahead of the advancing warm front, which arrived in part of northern New England during the evening of the 9th. High pressure anchored to the north of Maine dammed low level cold air up against the mountains and allow...
Flash Flood — Jul 18, 2023
Scattered showers and thunderstorms with heavy rainfall developed across the White Mountains and areas northward on the afternoon of the 18th. Moist air supported torrential rainfall rates between 2 to 3 inches an hour, all of which fell over saturated soils. Localized flash flooding resulted where storms trained over the same locations.
