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.

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.
