Tipperary, Offaly, Kilkenny and parts of Galway may experience temperatures in excess of 30C today as the country braces for a very hot day.
The parishes of Laois, Carlow and Westmeath will also experience highs of 30C as the warmest conditions will be inland.
Temperatures in Wexford, Mayo and Belfast are forecast to hit 28C, while Cork and Clare are set to hit highs of 27C.
Met Éireann’s status High Amber Temperature Warning for Leinster and Munster will be extended to the whole country from 12pm today.
The country’s weather warning for hot spells will also remain in effect until midnight on Monday.
Meteorologist Paul Downes said it will be slightly warmer today and will see temperatures rise again tomorrow.
The country experienced its hottest August day in more than 19 years yesterday when a temperature of 30.5C was reached in Carlow.
Met Éireann said the maximum temperature of 30.5C was reached on Thursday at Oak Park weather station, which also recorded Wednesday’s highest reading of over 29C.
Mr Downes said that August’s record high could be broken today and tomorrow.
Hottest August day on record, 31.5 °C recorded August 2, 1995 in Oak Park.
Mr Downes said there was a “growing chance” that could be surpassed in the coming days and Met Éireann would be monitoring the situation.
He said there was a slim chance Sunday’s status yellow high-temperature warning would be extended for Leinster and Munster, but that has yet to be confirmed.
The decision will depend on whether or not the country experiences thunderstorms on Sunday.
The high temperatures in the coming days can lead to heat stress, especially for the vulnerable population group.
There is also a high solar UV index along with a risk of water related incidents.
