The forecaster says that by Tuesday the low will have been taken up by the jet stream and will deepen significantly. More below Met Éireann chart. 

Looking ahead to Wednesday when the storm will make landfall, Met Éireann says the low pressure will have moved to the northern side of the jet stream and undergone further deepening.

The forecaster says Storm Agnes is likely to make landfall late Wednesday morning and a number of weather warnings have been issued in response. Met Éireann says these warnings are likely to be updated as further modelling data becomes available.

Met Éireann expects that the strongest winds are forecast to impact the south and south-east of the country. However, the latest guidance from its high-resolution ensemble prediction system, IREPS, demonstrates uncertainty in the exact track of Storm Agnes.

"We are monitoring the development of this storm closely and further updates to our warnings will be issued in the next 24 to 48-hours," says Met Éireann.

The national outlook is that Storm Agnes will clear away towards Scotland on Wednesday night but it will remain rather unsettled for the remainder of the week. More below tweet
