No Advisories in place.

The Alex Alerting Service is issuing a Category 3 Warning for Sligo, Clare, Galway and Leitrim from 13/07/2025 1300hr to 2100hr for severe thunderstorms and torrential rain.

Rainfall is expected to reach or exceed 20mm per 3hr or 6.6mm/hr, which is considered a medium flood risk. This is paired with high intensity thunderstorms over Castlebar, Sligo Town and parts of Leitrim and Roscommon.

There is no crosswind detected and so the possibility of this being a supercell storm is diminished. However, if you do spot a supercell forming, rotating clouds, or a funnel cloud forming, please inform AAS-ROI immediately and submit any photo or video evidence to www.aas-roi.com/private-submission

Avoid low-lying routes. Do not drive through floodwater. Remain indoors during lightning activity.

Wednesday

The Alex Alerting Service is issuing a Category 4 warning for heat from July 11th, 2025 through Sunday 13th of July 2025 from 20:00hr through 22:00hr nationwide.

Temperatures are expected to reach or exceed 31°C nationally, with exposed areas reaching 25°C nationally. AAS-ROI data shows a raise of upwards of 23°C in city cores, which may bring apparent temperatures of 41°C or greater during this time in Cork, Limerick and Galway, with Dublin potentially being the worst affected due to the size of the city itself. National humidity levels are anticipated to reach and exceed 84% due to partial or heavy cloud cover in places and AAS wishes to inform residents that this could potentially mark the hottest days of the year Ireland has experienced in the last 200 years, Based on brief research.

The Alex Alerting Service will continuously update this alert as further information becomes available.

Please attempt to resolve heat related issues before contacting the emergency services, only contacting them if you are alone and feeling lethargic or if your partner, spouse or co-habitant considers you are lethargic. Please remember that your health is of extreme importance, that you may not be able to cool down effectively unless you live on the coast with a stiff wind or have air conditioning at your property. Consider entering a store with air conditioning if you do not have any at your home and failing this, consider taking a cool shower though, not so cold that it will be shocking, and/or taking a bath with a few ice packs within to immediately cool down. AAS recommends releasing the water as you enter, to prevent hypothermia as your health is important.

6/4/24 - 10:20IST
Looking ahead from right now at 10:20am, It is going to be getting blustery across the country as wind gusts start to pick up. the sustained average is going to hold itself reasonably throughout the day, but is currently looking rather unpleasant for the most part with scattered showers throguhout.

This is a developing system, confirmed with UKV, ICON-EU and ICON. Identified with ECMWF. Currently UKV provides the highest resolution, but may not be 100% accurate. Its range is out on 29/02/2024 at 2359hrs. More details will become available later. 

20/02/2024

A Category 3 (Advisory type) alert is being issued as tomorrows gusts are expected to reach up to, and above 120kmh however, due to the weather models all disagreeing, I cannot place the full weight of a Category 3 warning into this one. This is a highly dynamic system which we are already beginning to feel today and with the uncertainty brought by the instability of this system, I cannot in the right mind issue a fully weighted Category 3 warning. However, do expect a lot of raina and alarmingly strong gusts of wind expecially in dublin and western seaboard areas that may come as a surprise considering the standing winds are between 20 and 40kmh. Do expect one hell of a downpour though, especially in cork and Kerry. 

18/02/2024 - 1300hr GMT

A Category 2 (High Cautionary) warning is in effect for high winds reaching up to 100km/h starting from 21/02/2024 at 02:00 through to 22/02/2024 at 16:00, followed by a warning for heavy rainfall nationwide from 21/02/2024 at 17:00 to 22/02/2024 at 06:00. While the probability is low, there is a potential for tornado formation; however, no supercell activity is currently suspected.

Advice: Secure outdoor items, stay indoors when possible, and follow safety instructions issued by local authorities. Remain alert to changing conditions and stay informed through official updates.

NOTE: A correction was made for the date for the wind warning

The Alex Alerting Service is issuing a Category 2 - High Cautionary (warning) for Wind/Rain warning for the areas of Sligo, Mayo, Clare, Galway, Donegal, Roscommon, Leitrim, Longford, Cavan, Westmeath, Meath & Louth from Tuesday 30/01/2024 at 2300hrs through to Wednesday 31/01/2024 at 1700hrs.

22/01/2024 - The Alex Alerting Service has issued its first warning for Jocelyn earlier today.  This storm is indicating damaging winds and torrential rain. At this time, there is no tornado warnings or advice tied to this system

23/01/2024 - It was not possible to fully authenticate the video of the tornado spotted. Remained blustery on the 22nd and damage was extensive. It is considered that a Category 4 Alert for Isha was well within the requirements, while only a few counties in the Republic of Ireland recieved an orange warning, the AAS firmly believes that a red warning nationwide wouldhave been appropriate. 

21/01/2024 - A tornado has been spotted at about 3pm In Castletownroche, Cork. Based on the video evidence, it appears to be a low scale funnel cloud that did not touch the ground. - AAS is currently waiting to confirm the incident. 

Winds are anticipated to begin to die off from 22:00 tonight, however actual conditions are liable to change over the course of the evening. 

After a few hours, the reported Tornado can have been reported at 12:32 in Ballygrillihan, Co. Cork today, 21/01/2024. I can confirm the incident as actual. 

20/01/2024 - The Alex Alerting Service is confirming and issuing the Category 4 - Critical Alert warning for Storm Isha, with projected winds of up to 80km/h and gusts up to 150km/h in places. Furthermore, a Tornado Watch is active at the moment for Sligo, Mayo, Leitrim and Cork for the time being, and charts are meing studied closely for indications of tornado producing systems if they arrise. The Alex Alerting Service Chat will enter emergency mode from 2200hrs today, this means any message into the chat from anyone will automatically result in phone call, and oyur phone will ring until you answer it. 

17/01/2024 - The Alex Alerting Service is upgrading this system, which will be likely named Isha to a category 3/4 warning for wind and rain. The timings are not known accurately at this time, but are being observed for changes and updates will be provided as necessary.  Presently, Met Éireann are tracking this system and some weather models are suggesting windspeeds up to 140kmh in places. Observe caution and follow the advice of local government and/or the AAS

15/01/2024 - The Alex Alerting Service is aware of a storm system approaching ireland. This system is comprised of 3 storms. The first 2 will be relatively mild compared to the third one. 

The third system is shapng up to be potentially destructive bringing with it sustained winds of 50 to 60 kmh and gusts up to 134kmh in Galway. This is comfortably on the low side of a category 1 hurricane. More updates will be issued in due course. 

AAS Has detected an approaching potential storm system for Wednesday 6th of December 2023 which has the ability to brings wind gusts over 100kmh in places of Cork and Kerry, along the entire west coast of Ireland the the south coast of Ireland. This will be a straight line storm part of a rotating system  with winds coming fromt he south east of the country. An alert will be pushed out if this system is confirmed to make landfall, and when accurate times are identified. 

Currently, It looks like this storm system might produce a yellow warning from Met Éireann during the week as it approaches.
