Hurricane Bertha has gotten a little press so far, but her evolution to extra-tropical structure indicates big things may be in store for the UK and parts of Europe.<\/p>\n
<\/p>\n
Hurricanes are compact, rarely more than 40 miles across where their strong winds reside, and slow moving. As a result they are easy to dodge. When these leave the tropics and form extra-tropical lows, they move faster and cover ocean wide areas. Dodging is impossible, and the seas have a chance to grow. In short, the tropical structure becomes far more dangerous to vessels as it fades from the headlines.<\/p>\n
<\/p>\n
The key to evaluating the likelihood of this occurring is in the 500mb weather charts. Three days ago they were indicating a possible trip across the Atlantic for Bertha. The 24 hour forecast above shows the same. Check out\u00a0http:\/\/www.opc.ncep.noaa.gov\/shtml\/A_brief.shtml<\/a> for the complete N. Atlantic run of surface and 500mb data. This will be an interesting weather event. And for those who are afloat in Bertha\u2019s extra-tropical path, keep a storm anchorage handy and extra ground tackle ready to go.<\/p>\n","protected":false},"excerpt":{"rendered":"
