A new intense windstorm possible for UK and Ireland later this week – GFS and ECMWF models in good agreement on new tropical development
GFS and ECMWF model guidance are currently in good agreement on the new tropical depression that may affect the British Isles and Ireland. Invest 92L, as the depression is currently designated, may strengthen into a strong storm to hurricane force cyclone as it crosses the Atlantic and approaches Ireland and UK.

Currently it is too early for detailed forecasts regarding the exact path of this potentially intense windstorm and future model runs may change significantly, but the system definitely warrants monitoring. Below is the ensemble forecast from the GEFS model for the next 5 days where trends are towards the direct hit for the British Isles where cyclone could move into Ireland or SW England. Stay tuned for further updates.
