Good day everyone!
This special statement pertains mainly to commercial shipping, fishing, and Bermuda given the extent of the wave heights. Though this should have no affect on the U. S., I thought it important for oceanic shipping and any yachtsmen sailing the open Atlantic. Information is based on the 06Z model runs.
The low I had mentioned in my initial statement is now developing and is located near 35.0N;70.0W, and is forecast to move toward the NE in about 24 hours. The ECMWF EPS cyclone formation probability still indicates the possibility of a sub-tropical entity. However, cyclone phase evolution modeling has come closer to this remaining cold core, or very borderline shallow warm core, and keeping it frontal in nature. The system is currently attached to a frontal boundary, with an occlusion attached to the center. For this to transition, it would need to detach from the front, or the front dissipate, and would at least have to become a partial warm core system. IF this is going to occur, it has approximately 24 hours from 09Z this morning to accomplish this before SST’s become colder and become below the threshold for STS development.
ATLANTIC VISIBLE SATELLITE LOOP
ECMWF EPS CYCLONE FORMATION PROBABILITY 00Z 23 APR.
NHC TAFB SURFACE ANALYSIS
The ECMWF indicates a well defined low pressure area, which is forecast to strengthen briefly, and then begin to weaken and dissipate as it moves quickly to the NE.
ECMWF MSLP ANOMALY FORECAST
ECMWF AND GFS CYCLONE PHASE EVOLUTION INFORMATION:
Both global models do indicate wind shear to relax to around 20 – 25 knots with a divergent pattern aloft. Given this, the process for any strengthening of the low will remain baroclinic.
Surface winds near and away from the center could reach Tropical Storm force, and wave heights could reach 14 – 20 ft near the center, with wave heights 8 – 10 ft near the coast of Bermuda.

I will continue to monitor this and update if necessary.
