Carlow Flooding December and January 2016

Heavy rainfall after Storm Frank and also on the New Years day resulted in flooding in many areas.

There were reports of a light Earthquake tremor off the Wexford Coast tonight, at 20:45,.

These reports were later confirmed by several people who felt the tremor.

The Irish Seismic Sensors don’t show any sign of Earthquake but Welsh Coast Sensor at Pembrokeshire shows it:

Feb 12th 2014 Storm

The great storm of February 12th 2014

February the 12th 2014 will go down in history for a day that saw a powerful and damaging storm. Some named the storm Darwin as the 12th was Darwins day

In this blog post I’ll look back at the days before the storm, how it was forecast and then track the storm as it moved through Ireland causing destruction.

On Thursday the 6th before the storm I posted some charts to my Facebook page showing a huge potential storm for Tuesday the 11th and then on Friday I posted another as a comment showing it for Wednesday this time! That chart turned out pretty accurate!

Screen Shot 2014-02-14 at 21.01.38

However over the weekend the charts began to show the system ending up South of Ireland not very intense at all e.g.

mldgmYW-e1392413318580

Then on Monday the charts had the storm back with a bang and heading our way, I posted to my Facebook page a chart along with a screenshot of Evelyn Cusack from Met Eireann who forecast Violent Storm Force 11 winds for Wednesday, their forecast included:

“Extremely windy or possibly storm conditions are likely on Wednesday, with heavy rain or sleet, and some local flooding.
Some structural damage is also possible. The exact track of the approaching low pressure is still not certain, so keep in tune with updates. ”

Screen Shot 2014-02-14 at 21.20.47

Violent Storm Force 11 is sustained winds of 103–117 km/h

Some charts were really starting to show serious winds Monday night such as

Screen Shot 2014-02-14 at 21.21.15

On Tuesday night I issued a Weather warning as charts continued to show damaging winds.

Screen Shot 2014-02-14 at 21.56.21

Late Tuessday night Met Eireann upgraded their warning for Cork and Kerry to Red Alert with gusts up to 160km/h, the warning was Orange for many other areas with remaining areas Yellow.

Screen Shot 2014-02-14 at 21.59.35

The storm made landfall early Wednesday morning and Cobh saw gusts of 50 knots or 92.6km/h by 7am as the image below from http://86.43.106.118/cobh-spike.html showed

cobh12th

By 8am ESB Powercheck site was showing power outages in Kerry with Sherkin Island reporting a gust of 131km/h, the storm was clearly visible on the sat images.

storm12th0800

As the eye of the storm crossed Cobh the winds dropped off at the weather station there but by 9am Roches Point had recorded a gust of 135km/h.

By 10am winds were picking up again in Cobh as the eye cleared and the second intense phase of the storm moved in with the strongest winds to the South of the eye.

storm12th1000

My station in Tullow hit 98.2 km/h at 10:09am as the front end of the storm hit.

By 11am reports started to surface on Twitter of a Tornado in Roscommon and the Kinsale Energy Platform off the south coast was reporting sustained winds of 118km/h and gusts of 140km/h.

By 11:30 there were reports of structural damage in Dingle

The eye of the storm was very defined now.

By noon more reports of damage were been tweeted including damage to a school roof in Bishopstown Cork, as Sherin Island reported a gust of 155km/h!!

Met Eireann upgraded earlier warning:

“STATUS ORANGE
Wind Warning for Dublin, Kildare, Louth, Wicklow and Meath
Upgrade to earlier warning.
Extremely windy weather will sweep up from the south during today, Wednesday.
Westerly winds 50 to 65 km/h will gust to 100 to 130 km/h.”

By 12:30 Twitter was becoming alive with reports and photos of tress down in Kerry and Cork including Cork City

By 1pm reports of trees down and structural damage were all over Twitter and 95,000 were already reported to have lost power.

Also by 1pm the Kinsale Enerhy Platform off the South coast recorded a Gust of 96 knots, that is 178 km/h!

Limerick was now seeing the peak of the storm with images of vehicles damage appearing on Twitter

Pressure was falling rapidly and winds increasing at Wexford Harbour at 1pm

By 2pm Shannon Airport had closed with a plane tipped over and UCC had issued a lock down notice. Shannon recorded the top Gust inland at 158 km/h!

Screen Shot 2014-02-15 at 15.04.21

The storm was now moving very quickly up through the country with my weather stations recording 109km/h Gust at 2:17pm.

At this stage I called Liveline for them to warn people of what was happening.  A pocast is available at http://www.rte.ie/radio/utils/radioplayer/rteradioweb.html#!type=radio&rii=9%3A20524310%3A53%3A12%2D02%2D2014%3A

Winds peaked in Kilkenny with KilkennyWeather.com recording 133.0 km/h  at 2:57pm from WSW, bringing down hundreds of trees in the area and Kilkenny County Council declared a state of emergency as all major roads were blocked.

Carlow peaked at 125.9 km/h in Oak Park just after 3pm with the South of the country seeing the most damage.

By 4pm 260,000 ESB customers were without power

By 5pm Dublin Airport has seen a gust of 122km/h

I also featured on the Joe Duffy show the following discussing the show and Long Range forecasts

Kinsale Energy Gas Platform recorded a maximum wave height of 25 metres this afternoon (Wednesday 12th February).Apart from being a record at that location, it is also the highest maximum wave height recorded in Irish coastal waters (the previous record being 23.4 metres at the M4 buoy off the Northwest coast).

Nasa’s image from Thursday morning shows #StormDarwinclearing the to the North East of Ireland while the monster winter storm that brought icing to the U.S. southeast moved northward along the Eastern Seaboard and brought snow, sleet and rain from the Mid-Atlantic to New England on February 13. A new image from NOAA’s GOES satellite showed clouds associated with the massive winter storm stretch from the U.S. southeast to the northeast.

Estofex Forecast

Estofex Forecast for tomorrow includes a risk of an isolated strong tornado event over the SouthEast!

Details:
“From noon to the evening hours, the triple point somewhere between SE-Ireland and C-UK becomes of interest as dry slot draws near from the SW. Interaction of both features could result in a few vigorous updrafts. This scenario is also backed by the favorable placement of a 50 m/s (plus) 500 hPa jet streak. LL flow won’t be as intense as further south, but high SRH-1 and low LCLs point to an isolated tornado threat… next to severe wind gusts and marginal hail.
Further south, the dry slot probably lowers thunderstorm probabilities, but an isolated event can’t be ruled out over NW France and most of C/S UK as BL moisture remains adequate with mixed-layer mixing ratios in excess of 5 g/kg. Spotty pockets of EL temperatures between -20 and -30 °C also support the idea of ongoing convection potential. Despite lack of confidence in a forced line of storms, any shower/thunderstorm event could support downward momentum transport of very intense winds (e.g. 850 hPa winds aoa 45 m/s with SRH-1 well in excess of 400 m^2/s^2 !). Once again it will be hard to distinguish between the background gradient flow and convectively induced wind gusts, but convection could certainly add a localized damaging wind gust risk at the surface.
Despite the ongoing wrap-up process of the thermal wave, this depression certainly features an higher tornado risk compared to the past events. Extreme LL shear and some modest onshore LLCAPE back that idea and an isolated strong tornado event can’t be ruled out especially over SE-Ireland, SW-S and C UK.”

Cork City is at high risk of flooding:
CORK CITY TIDAL FLOOD ALERT …

A tidal surge & strong south to south easterly winds are predicted over the next number of days. These factors combined will increase the tide levels over the natural tide levels.

During this period, prior to and after these tides, there is a danger of Tidal Flooding in the City.

It is possible that flooding may occur in the low lying areas of the City Centre including in particular South Terrace, Trinity Bridge, Rutland Street, Cotter Street, Stable Lane, Union Quay, Morrisons Quay, Proby’s Quay, Frenchs Quay, Crosses Green, Sharman Crawford St, Wandesford Quay, Lavitts Quay, Kyrls Street & Kyrls Quay, Coal Quay and Lapps Quay

Other Areas at potential risk are South Mall, Oliver Plunkett Street, Pembroke St., Princes Street, Marlborough Street, Cook Street, Winthrop Street, Kennedy Quay, Centre Park Road, Monahan’s Road, Georges Quay, and the low lying areas of the City Centre.

Householders and businesses should take Precautionary Measures to protect property.
