Tropical Storm Bertha (03L) over Jamaica

The second hurricane of the 2014 Atlantic hurricane season, Bertha was relatively mild-mannered but well-travelled. The storm first formed in the waters east of the Lesser Antilles, with first advisories posted on August 1. After sweeping across the Lesser Antilles and passing near Puerto Rico, Bertha crossed the Dominican Republic on August 2 as a weak tropical storm, with winds of 45 mph (72 km/h). Despite its relative weakness, there were reports of widespread power outages and some flooding in Martinique, Puerto Rico and The Dominican Republic.

After passing through the Bahamas and the Turks & Caicos Islands, Bertha strengthen to a Category 1 hurricane on August 4, with maximum sustained winds of about 80 mph (128 km/h). It weakened as it sped along off the coast of the eastern United States, and was reported as a post-tropical cyclone by the National Hurricane Center (NHC) on August 6.

Although a much weakened system, the remnants of Bertha moved across the Atlantic Ocean heading towards Europe, where a jet stream has pushed the storm (now called an Atlantic Storm) towards the United Kingdom at up to 100 mph (161 km/h). The UK’s Met Office has issued a Yellow warning for severe weather for Central, Tayside and Fife, East Midlands, East of England, Grampian, Highlands and Eilean Siar, London and South East England, North East England, North West England, Orkney and Shetland, South West Scotland, Lothian Borders, South West England, Strathclyde, Wales, West Midlands, Yorkshire and Humber, as well as flood alerts in Anglian, Southeast and Southwest. A Yellow warning means to be aware that severe weather may occur.

Forecasts predict heavy rains, with the possibility of 1.9 inches of rain in a few hours, localized flooding, gusts of up to 70 mph (112 km/h). That rainfall is nearly the total average rainfall for the entire month of August (2.2 in).
