Warm spring may result in gentle breakup

Following the warmest March Alaskans have ever felt, forecasters are predicting a mellow transition from ice to water for most big rivers in the state. Things don’t always go that way during spring breakup, when chunks of river ice freed from the cold grip of winter can lock up in river bends and back up water into communities.

Reconstructing America’s longest water level and instrumented flood record in Boston

By Jan Lathrop Using newly-discovered archival measurements to construct an instrumental record of water levels and storm tides in Boston since 1825, researchers report that local averaged relative sea level rose by nearly a foot (0.28 meters) over the past 200 years, with the greatest increase occurring since 1920. The work also highlights tides and their significant effect on flooding in the city. The evaluation of storm events since 1825 …

Seismometer readings could offer debris flow early warning

Instruments designed to record earthquakes revealed information about debris-flow speed, the width of the flow and the size of boulders carried by the January 2017 mudslide in Montecito, California, and the location of the event, suggesting that the current generation of seismometers in the field could be used to provide an early warning of an incoming debris flow to residents in mudslide-prone areas.

Schools were closed, roads washed out, and many other closed.  I mentioned yesterday that the water temps in the Atlantic are at record levels, and it’s hard to …
