Met Éireann has issued a warning of drought or near-drought conditions for the entire country as temperatures remained high in most parts of the country today.

A Status Yellow advisory is in place with Met Éireann saying, "with little or no rain forecast for most areas over the coming week, drought or near-drought conditions are expected to develop more widely across Ireland".

A separate Status Yellow high temperature warning is in place for Munster and Leinster.

Temperatures in excess of 27C are expected in parts of Leinster and Munster tomorrow.

Temperatures dropped slightly today but still reached just under 28C across the midlands and west.

Met Éireann has said that the country is in a "heatwave situation". A heatwave is defined as five continuous days of temperatures above 25C.

AA Roadwatch is advising motorists to be aware of melting tar on roads throughout the country.

Road surfaces can become slick in the heat with secondary roads most likely to be affected.

Councils have been treating some of the worst affected areas by sprinkling and rolling fresh chippings on the road surface.

Meanwhile, food producers are also under increasing pressure.

Prices for crops such as broccoli could rise as yields are down, according to Ireland's largest broccoli grower.

Speaking on RTÉ's CountryWide programme, Paul Brophy said the sustained heat was affecting all areas of farming.

Mr Brophy said: "Reserves of water that people would have are becoming more and more fragile every day and it's across all crops not just what we're growing.

"It's all producers."

Hosepipe ban in Dublin to counter water shortages

Restrictions on water supplies are in place in many parts of the country and yesterday Irish Water announced that it will impose a ban the use of hosepipes in the Greater Dublin Area from Monday.

The company said the ban would be in place until 31 July, but it would keep the situation under review.

It added that it may have to extend the period of time the order is in place.

The ban will apply to the use of water drawn through a hosepipe or a similar function. Those found in breach of the ban could face a fine of €125.

Irish Water also said that the number of water zones under restriction is at 28, and the number of "at risk water zones" is at 128.

The utility said that it is "operating on a knife edge" and urged consumers to continue to conserve water.
