Debi is the fourth named storm of the season.
Weather warnings are in place for large parts of the UK ahead of the arrival of
Storm Debi on Monday.
On Monday morning (November 13), the storm will hit northern England and parts of north Wales.
The risk of flying debris and large waves means there is a possible danger to life in some areas, with the storm also potentially bringing flooding, travel delays, power cuts and even tornadoes.
Storm Debi developed here in Ireland, where red weather warnings were in place up until 9am on Monday. The storm is now set to sweep over the UK and weather warnings have been issued across the country.
In Ireland, a Status Yellow Rain and Wind Warning is in place for the entire country until 3pm today, with heavy rain and a chance of embedded thunderstorms and hail forecast. Earlier Status Red wind warnings for east Galway, Roscommon, Kerry, Limerick, Tipperary, Clare, Dublin, Kildare, Laois, Louth, Meath, Wicklow, Offaly and Westmeath have expired.
Tornado research organisation issues alert for Storm Debi
On the risk of tornadoes in particular, the UK’s Tornado and Storm Research Organisation (TORRO) has issued a Severe Weather Forecast Tornado Watch alert.
The organisation have said winds could reach speeds of 160kmph, with the potential for 20mm hailstones as well.
A spokesperson said, via the
Mirror: “A rapidly deepening Atlantic low, named Storm Debi, will move into the RoI (Republic of Ireland) and Northern Ireland overnight. The frontal system will cross the area after midnight and through Monday morning (as well as much of the rest of the UK and RoI).
“Very high winds associated with the low will affect parts of the RoI, and portions of the UK, catered for by warnings from the national weather services in both jurisdictions.
“This forecast is concerned with the risk of one or two tornadoes, associated with the passage of the cold front of the system. A surge of dry mid and upper level air will overspread the front into Monday morning, associated with a pronounced upper trough. Strong lifting associated with this should cool mid-levels enough to allow convection to develop – perhaps as a strongly forced line over the RoI into SE N Ireland, and then a more broken line into Wales/N England and points east.”
They continued: “Strong shear, both deep layer and low level, will be present, enough for a few storms to become organised, perhaps with low-topped supercells. The very high low-level shear may allow for the development of a few tornadoes.
“The highest chance would appear to be in a line from SW RoI, through parts of mid/N Wales into the Midlands and eastern England, near the triple point of the system. However, the box is somewhat larger, just to cater for the chance of development elsewhere.
“Additionally, strong straight-line gusts are possible too, associated with convection (as well as with the gradient flow from the storm, as mentioned above). Occasional CG lightning (cloud-to-ground lightning) is possible too. Finally, a few incidences of hail cannot be ruled out, especially with stronger cells – perhaps close to severe levels in one or two places.”
The Met Office has issued
amber warnings for strongs and disruptive winds for parts of Northern Ireland and north west England.
The UK has already been battered in recent weeks by Storm Ciarán, which caused flooding and disruption, and Storm Babet, which killed seven people across the UK.
