Good Afternoon Colleagues,
The main focus of attention in the next 60 hours (as far as midnight Sat/Sun) remains the risk of coastal flooding centred around tomorrow’s high tide shortly after midday.
The winds accompanying the tide (S to SW’ly in direction) will gust to between 50 and 70mph along the coast with max speeds nearer 40-50mph inland, the period of strongest winds occurring from around 0800/0900 to 1400/1500.
A Yellow warning for wind (low likelihood of significant impacts) remains in force for the whole of the Northwest coastal strip for tomorrow. For a fuller explanation of the coastal flood risk please refer to this morning’s Flood Guidance Statement which shows the NW coastline at Amber (medium flood risk) tomorrow with a medium likelihood of significant impacts resulting.
Lighter winds on Saturday but still the risk of a few sharp showers, especially during the morning.
Later on Saturday night and into Sunday morning a new belt of rain and strengthening winds will move up across the whole region. The largest rainfall totals will be across north Lancashire and Cumbria where some minor impacts are possible. The main risk of disruption will again, however, focus along the coastal strip where the combination of strong S to SW winds and still high tides will result in a renewed risk of coastal flooding. To this end a new Yellow alert has been issued for the period 0900 to 1800 Sunday whilst today’s Flood Guidance Statement has retained the entire NW coastline at Yellow (low flood risk) throughout the weekend and into Monday, to allow for any renewed coastal impacts, the strong winds of Sunday likely to persist through much of Monday as well.
A reminder that all current warnings and alerts can be viewed on the Met Office website. A further update will be issued tomorrow morning.
With kind regards,
Alan Goodman; Met Office Advisor (Civil Contingencies)
