IRELAND may be battered by Storm Callum and the remains of Hurricane Leslie this week.

Carlow Weather’s Alan O’Reilly shared a chart last night and said we could be set for a “serious weather event” on Friday.

Gusts “in excess of 150kmh” may hit parts of the country on October 12 – meaning a red alert could be on the cards.

And this afternoon, he took to social media and said Leslie could follow the "intense storm".

He wrote on Twitter: "GFS 6z shows the system which could be called #StormCallum on Friday followed by the remains of #HurricaneLeslie on Saturday!

"Details will change over the coming days so stay updated.

"Heavy rain with both systems too which could cause some spot flooding along with coastal flooding. #StormCallum #HurricaneLeslie."

The warnings are given a colour to reflect the seriousness and likelihood of the impact, ranging from yellow, orange and red.

Red is the most serious of the weather warnings and means "extreme weather" is expected.

After the possible Storm on Friday there is then a chance that the remains of #Leslie will head our way for the Weekend but path is still uncertain and intensity doesn’t look as bad the system that could be named #StormCallum Friday. A wet and windy end of week ahead though! pic.twitter.com/nol5FnqjbK — Carlow Weather (@CarlowWeather) October 8, 2018

Red warnings are issued for wind when there is a danger to life from flying debris, and widespread property damage and disruption to travel and power networks are forecast.

Gust speeds must hit "in excess of 130 km/h" before Met Eireann can issue a red weather warning for wind.
