Guardian: Scotland and northern England were battered by driving rain and winds of up to 50mph on Monday as the tail end of hurricane Bertha swept northern Britain. Stormy conditions are forecast across Scotland, Wales and northern England for the next few days, with amber flood warnings covering large parts of the UK. The small port town of Lossiemouth in Moray, Scotland, was deluged by more than a month's rainfall in 12 hours by early Monday morning, while Aberdeenshire recorded gusts of 50mph. Wales...

Hurricane BERTHA Forecast Discussion Number 17

Issued at 1100 PM EDT MON AUG 04 2014 000 WTNT43 KNHC 050240 TCDAT3 HURRICANE BERTHA DISCUSSION NUMBER 17 NWS NATIONAL HURRICANE CENTER MIAMI FL AL032014 1100 PM EDT MON AUG 04 2014 Bertha certainly does not look like a typical hurricane in satellite imagery this evening. The center has become partially exposed to the northwest of the deep convection. A NOAA Hurricane Hunter aircraft that recently investigated the cyclone observed flight-level, SFMR, and dropsonde winds that all supported hurricane intensity late this afternoon. Since that time, the organization has degraded a little and it is possible that Bertha has weakened below hurricane strength. However, new convection has recently formed just east of the center near where the strongest winds were measured earlier. Therefore, the initial intensity is held at 65 kt. This could be generous, but it is best to maintain hurricane status until the the next Hurricane Hunter aircraft examines the storm around 0600 UTC. Bertha is forecast to gradually weaken during the next day or two while it moves into an area of increasing southwesterly vertical wind shear and over decreasing sea surface temperatures. On Wednesday, the cyclone is expected to interact with an approaching mid-latitude trough and Bertha is forecast to become an extratropical cyclone over the North Atlantic shortly thereafter. Fixes from the aircraft show that Bertha is moving a little faster and has turned north-northeastward this evening. The track forecast reasoning remains unchanged. Bertha is expected to accelerate northeastward during the next day or two between a mid-level ridge over the western Atlantic and a deep-layer trough moving off the northeast United States coast. After Bertha becomes a post-tropical cyclone in 48 to 72 hours, it is forecast to turn east-northeastward in the mid-latitude westerly flow over the north Atlantic.
