Arising from current weather patterns, an extreme forest fire risk is deemed to exist in all areas where hazardous fuels such as dead grasses, heather and gorse exist.
An anticyclone of 1038hPa centred over the North Sea will track steadily eastwards and generate light to moderate easterly airflows over Ireland during the next 24 hours, consistent with a ‘Type A’ fire weather pattern. This type of pattern has previously been associated with extreme fire behaviour under Irish conditions. EFFIS Fine Fuels Moisture Code is now in excess of 85 and Initial Spread index values are in excess of 10 across much of Ireland indicating high fire spread potential and difficulty of suppression in typical upland fuels. Fire behaviour will be influenced by light to moderate easterly and south easterly winds that may exceed 20km/h in coastal areas. Fire behaviour may be moderated by increased live growth in places.
Overall Forest fire risk is likely to be compounded by ignitions risks associated with expected high levels of public activity in fire prone areas during the Bank Holiday Weekend.
