GAV'S FLASH! Here Come's Bertha? Good evening, Tropical storm Bertha is currently bearing down on the Bahamas and will moving northwards off the coast of the eastern United States through this week.. You an see the forecast track of tropical storm Bertha here.... http://www.nhc.noaa.gov/refresh/graphics_at3+shtml/173949.shtml?5-daynl?large#contents By Friday the then sub tropical storm Bertha will be past New Foundland and moving eastwards out into the central northern Atlantic. With an unusually strong jet stream for the time of year many of the global computer models are keen to move a vigorous area of low pressure towards the British Isle's at the end of next week and possibly even move it into the UK next weekend. The GFS 168hr chart for next Sunday show's quite an autumnal looking area of low pressure at 990mbrs in the central Atlantic. ![]() By the start of next week - Tuesday 12th August the area of low pressure that WAS sub-tropical storm Bertha is moving into the UK as a vigorous area of low pressure. This would bring heavy rain and gales to parts of the country. ![]() The Canadian GEM shows the low pressure making quicker progress across the North Atlantic though the later stages of next week. On Thursday 7th August the GEM show's the sub-tropical storm off the coast of New Foundland. ![]() By Sunday 10th August the GEM show's the low pressure to the west of the United Kingdom, not as an intense storm, but certainly active enough to be producing a lot of heavy rain and the potential for gales in the north and west especially. ![]() The ECMWF is perhaps the most incredible chart of all for Sunday 10th August showing an intense, 980mbr storm sitting just to the west of the country! This chart wouldn't look out of place in the depths of the storm season from October to January ![]() Obviously the ECMWF solution of the most extreme of the top three and would bring severe gales with torrential rain to many parts of the country. The ECM is currently throwing out quite extreme charts for this period though (this morning's 00z chart for next Sunday was even more extreme, perhaps indicating temperatures of 30c with severe gales and torrential rain?) Whether things turn out as extreme as the ECM is indicating, it certainly seem's that the remains of tropical storm Bertha may well be paying us a visit in about a week's time with some unusually unsettled summer weather moving in. GavsWeatherVids will keep you posted through the week. Gavin Partridge. 3/8/14 Source .................. http://www.gavsweathervids.com/ |
