THE WINDS were brought in by a band of low pressure crossing northern England and Scotland from the South-west, according to the London Weather Centre.

A principle of mechanics known as the Coriolis effect of the earth's rotation, named after a 19th- century French civil engineer, dictates that the low pressure will be accompanied by swirling winds moving in the same direction, but following a more southerly path. This meant that the region hardest- hit was from the South-west to the Midlands. Although the winds were prolonged, extreme gusts caused the most damage.

The strongest were recorded at Pembrey, Dyfed, at 98mph. In London the winds reached 76mph (66 knots), and in Aberporth, Dyfed, 95.6mph (83 knots). London's previous highest December figure was 77.2mph (67 knots), in 1977. During the storm in October 1987, gusts of more than 100mph were recorded across Britain.
