Weather oddities — what a coast remembered before it could forecast

Why weather stories were useful

Mrs. Brittingham’s starting point is that weather fashioned the fate and fortune of seamen and farmers from the moment anyone first hoisted a sail or ploughed a furrow, and that people living on a rural seacoast have a particular sensitivity to it. She wrote that it is easy, with modern forecasting, to forget how recently that was not available.

In the absence of forecasts, a community’s accumulated memory of extreme events was the closest thing to a risk model it had. Knowing that the bay had frozen hard enough to walk on, or that a particular storm had put water into particular streets, told you what was possible. Anecdote was doing the work that data does now — badly, but it was what there was.

The three things this coast has to fear

First, the northeaster. Delaware Bay is exposed to wind from the north-east, and a sustained blow piles water into the bay and onto the shore. This is the weather the breakwaters of 1828 were built to shelter from, and the reason ships at anchor off Lewes were in danger before them.

Second, ice. A hard winter closes a working port: pilots cannot work, boats are crushed or frozen in, and a bay town’s whole economy stops. Exceptional freezes are the events that get remembered longest in northern port towns, because they are the ones that idle everybody at once.

Third, the slow one. Cape Henlopen is a moving landform, and storms accelerate what is already happening. The Cape Henlopen Lighthouse was badly damaged by a storm in 1920, abandoned in 1924 and fell into the Atlantic in 1926 — but the real cause was a century of sand walking away beneath it. Weather finished a job erosion had been doing all along.

What has changed, and what has not

Forecasting has changed almost everything about how this coast experiences weather. A northeaster is now a scheduled event: it arrives with a name, a track and several days’ warning, and people move their boats.

What has not changed is the underlying exposure. The town still sits at the mouth of a funnel-shaped bay on a low, sandy, mobile shoreline, and the cape is still migrating. The concrete towers of Fort Miles are being undermined by the same processes that took the lighthouse. Better information about the weather has not made the geography any different.

“Weather conditions have fashioned the fate and fortune of seamen and farmers since men first hoisted a sail or plowed a furrow. People who live in rural areas along the seacoast have a special sensitivity to the weather and its effects upon their lives and livelihood.”
