Satellite images and tracking maps of Severe Cyclonic Storm Yaas 2021, May 22 - 27. Max wind speed 120km/h.
Satellite imagery shows the convective structure now moving over land and beginning the decaying process as it transits over the rugged terrain.
The initial position is placed with high confidence based on the LLCC feature in the composite weather radar from Paradip, India, and analysis of local weather observations.
Analysis shows Yaas resides under weaker poleward outflow aloft and strong wind shear (30-35 knots), contributing to the rapid decay as the storm dissipating in 24 hours.
Forecast guidance are in fair agreement with a cross-track spread of 54 km at 12 hours due to the far sole right outlier of AFUM.
The model spread widens to 122 km with AFUM in 24 hours or 54 km without, lending overall high confidence to the JTWC forecast track that is laid just to the left of the model consensus to offset AFUM.
This is the final warning on this system by JTWC. The system will be closely monitored for signs of regeneration.
