Get ready Ireland, the sun is set to visit and show itself for once, but there’s no doubt it’ll be bringing with it unprecedented and even dangerous heat.

Met Éireann, Ireland’s weather service, has issued a Status Yellow temperature warning so far, but this could quickly turn into a red alert this week as temperatures will reach the high 80s (30 Celsius).

A yellow warning entails temperatures around 80°F (27°C), while an orange warning refers to temperatures in excess of 86°F, but the red warning refers to prolonged weather above 86 for at least two nights.

Met Éireann is telling the public that a red weather warning means that they should take action to protect themselves from the intense heat and UV rays.

“The issue of RED level severe weather warnings should be a comparatively rare event and implies that recipients take action to protect themselves and/or their properties; this could be by moving their families out of the danger zone temporarily; by staying indoors; or by other specific actions aimed at mitigating the effects of the weather conditions,” Met Éireann told the public.

Currently, temperatures are only increasing over the next couple of days with meteorologists predicting even hotter weather. They are unsure of how long this heatwave could last since there is no end in sight.

The heatwave, so far, has led parts of Ireland to start rationing water as supplies are at risk amid these high temperatures. Dublin, Donegal, Athlone, and other areas have been asked by the Irish water utility to conserve water as supply is at serious risk in these areas.

According to the Irish Mirror, the utility company may have to introduce night-time restrictions to tackle the issue.

Tuesday is looking to be the hottest day this week, as high pressure settles in, which will leave most areas in the country very sunny. The only place to get a break from this scorcher would be to stay close to the coast, where at least the afternoon sea breezes will provide people with some relief.
