Hurricane gusts raked the southeastern U.K. on Oct. 15-16, 1987, as a powerful, fast-hitting storm tore through the region.
The "worst storm since 1703" killed 18 people, the BBC News website said.
The incident was, for the British insurance industry, the costliest ever for weather-related claims, according to the BBC.
Extreme winds, locally clocked above 100 mph, devastated woodlots and city shade trees.
Parts of London had winds of at least 70 mph, or almost hurricane force, according to the BBC. But the southeast corner of England bore the brunt of the storm, as gusts reached between 90 and 122 mph.
At the highest point in Kent, Toys Hill, about 98 percent of a woodland that included centuries-old beech trees was lost.
The UK Met Office's chief meteorologist called the storm a "once-in-300-year event".
One notorious aspect of the storm was that the Met Office was caught "off guard," failing to foretell the devastating nature of the blow.

The plum rains are known as "meiyu" in China, the "baiyu" or "tsuyu" in Japan, and the "jangma" in the Koreas. The heart of the plum rain season stretches from early June to mid-July, with a tendency to shift south to north across the affected area.
In the wake of the mid-June cloudbursts, most of Pakistan to northwestern India last week saw a return to dry, hot weather typical of the weeks leading up to the Monsoon onset. It was as if the Monsoon withdrew to its "normal" position for the latter half of June.
The 38.5 degree C (101 degrees F) reading Tuesday in Ajaccio, Corsica, may have been tops in Europe.
Monsoon Onset was June 13th, 2013, in Delhi, almost two weeks earlier than average. The June 15th onset at Karachi and Islamabad was more like three week ahead of schedule.
In Pakistan, hit-or-miss downpours missed the Sindh capital, Karachi. One did hit Pad Idan, where it left 60 mm of rain Wednesday. This was more than 20 times greater than the normal June rainfall.
It is still possible that this scenario is over wrought as to the intensity and spread of rain in Pakistan and northwestern India. However, it is the hunch of the present forecaster that some very unusual weather is going to unfold in the Subcontinent during the next week!
