depression in real time. In post season reanalysis 07E was upgraded to a tropical storm. Douglas (08E) 20-29 July 954 mb, 115 knots Track forecast errors were very low for this hurricane, particularly at shorter lead times. For example, 3- and 4-day errors were less than half of the 5-year running mean

, marking a return to more traditional autumnal weather. This rainfall – associated with the remnants ex-Hurricane Lee – will be heaviest and most persistent across parts of Wales and northwest England. Some surface-water and river flooding is possible in these areas, with a Yellow weather warning in force

These changes exert an influence lower down in the atmosphere and ultimately on our weather. How does the Polar Vortex affect our weather? A strong polar vortex favours

, primarily as a result of ocean warming and melting of land-based ice. Even this relatively modest rise has been linked to substantial increases in coastal flood risk. For example, one study looking at the severe flooding in New York caused by Hurricane Sandy found that recent sea level rise had made
