A few NWP models (e.g. IFS and ICONEU) suggest the development of a low-level cyclone under the blob of deep convection in the Libyan Sea during Tue 15/09 and early morning on Wed 16/09. By the time of issuing this outlook (Mon 14/09, 20z), no visible near-surface vortex exists in the Gulf of Sidra. In addition, there is no strong mid/upper-level vorticity in the analysis maps to support the development of a strong surface cyclone and eventually support these NWP model scenarios that deep convection will be able to diabatically intensify this cyclone by generating large values of low-level PV. Even though a tropical transition of a cyclone is very unlikely to happen by the end of this outlook, this interesting set-up needs to be monitored closely for the following 48 hours.
