A weather expert has shared warning signs that show the potential upcoming Sudden Stratospheric Warming (SSW) event could be a 'major' one.
It was a major SSW that brought the ‘Beast from the East’ to Ireland five years ago, causing the country to come to a standstill with widespread heavy snow.
Independent Irish forecaster Alan O’Reilly, who is monitoring the possibility of an SSW event, said there are early signs such as a "warming up in the Stratosphere" and the direction of the winds that mean the SSW event could also be a "major" one.
