For only the second time ever, meteorologists are using Greek letters to name Atlantic Storms.
This, after the list of 21 names was exhausted with the formation of Tropical Storm Wilfred today.
Shortly after Wilfred, another storm developed in the Northern Atlantic, and is heading in the direction of mainland Europe.
This system has been named Sub-Tropical Storm Alpha.
There are no coastal tropical cyclone watches or warnings in effect at this time, however interests in Portugal are monitoring its progress.
Alpha is carrying maximum sustained winds near 85 km/h, with little change in strength is expected before landfall.
It is forecast to move across west-central Portugal during the next couple of days.
The only other time the list of names was exhausted was in 2005, where six storms were named using the Geek alphabet.
