Chesil – 10 March 2008 Tidal elevations from Weymouth (NSLTF (POL)) This intensive storm resulted from the development of an extensive, complex, deep low pressure system (central pressure 946 hPa), which transited rapidly across the southern half of the UK, filling slightly to 966hPa (Figures 5 to 6). The storm generated a long-lasting storm surge of nearly 0.8m at Weymouth. Although the peak of the storm occurred 4 hours after HW, the conditions at High Water (about 09:00), saw waves in excess of 4m, a near-equinoctial spring tide, and a storm surge of 0.63m to give a combined SWL elevation (at Weymouth) of 2.11m OD. Waves were from the SW, which is the direction of highest exposure at Chesil. Tidal elevations from Weymouth (NSLTF (POL))
