ECMWF & GSF are now having similar outcome for the System developing in the South Arabian Sea. GFS is consistent with the forecast track compared to 24 hours earlier, however, the latest ECMWF shows that it would take more time to reach towards Saurashtra Gujarat compared to 24 hours ago forecast track. This System is expected to become a Cyclonic Storm and if the track towards Gujarat & Saurashtra materializes, farmers should be cautious. Western Disturbance as well as future WD during the forecast period could affect the final outcome this System. Forecast outcome can change and updates will be given as and when available.
