" This shows us that the only gradient exceeding 0-12 on the 16th, which was not followed by a very decided fulfilment, was that of West 13 from Weymouth to Liverpool. The predominating storms on the South coast of England were Southerly, and had very little Westing in them. They gave, however, abundant indications of their approach in the change of gradient of (+ 11) in the direction from London to Penzance. " On the whole it will be seen that on the morning of the 16th there was a gale at only one station, South 10 at Valencia, and on the morning of the 17th there were only two, viz., 9 at Plymouth, and 8 at Portsmouth, while between these two dates gales were felt at 10 stations which might reasonably have been foreseen by an examination of the morning reports of the 16th, on the principles laid down in the preceding pages.
