Both warnings bring the threat of localised flooding and dangerous travel conditions. Met Éireann's forecast for this week is rather gloomy as the national forecaster predicts "generally unsettled conditions" with frequent and "above average" rainfall. Starting with this morning, there is persistent rain across the south and east of the country, drier in the west and north. That rain will clear northeastwards as the morning progresses, but more showers will arrive in from the west, becoming more long-lasting.
The first warning is valid from 2pm today until 9am tomorrow morning and promises to bring "persistent" and "heavy" rainfall, the forecaster said. It applies to counties Cork, Kerry and Waterford and threatens localised flooding and difficult travel conditions. These three counties were subject to the previous rain warning which expired this morning. Another warning has been issued by the forecaster for Wexford. It begins at 8pm on Sunday evening and lasts until Monday morning, 10am.
France is currently in the grip of a cold snap which blanketed large parts of the country in snow on Thursday. The 'manteau blanc' (white coat) was caused by a polar vortex which has become stuck over the country leading to unusually cold temperatures and ice and snow in lowland areas. According to Météo France, this will continue into the weekend, with Saturday predicted to be the coldest day.
The now Category 4 Hurricane Humberto is currently tracking northeastwards from the southeast coast of America towards Ireland at around 130km/h, but is expected to slow significantly before reaching our shores. However, weather models say it will become re-energised by the jet stream - a fast-flowing current of air above the North Atlantic - which will bring stormy conditions from Friday morning until late evening.
The National Weather Service warns that a dangerous heat wave, combined with high humidity, will blanket much of the central and eastern US, with temperatures possible above 100°F.
