Coastal 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. Portland had its all-time storm tide, posting a record flood water level (records 1912-...

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...
