Tropical Storm Eugene Forms South of Baja California

A distinct center of circulation consolidated within a broader area of low pressure south of Baja California on Friday and the National Hurricane Center classified the system as Tropical Storm Eugene.  At 5:00 p.m. EDT on Friday the center of Tropical Storm Eugene was located at latitude 11.9°N and longitude 111.2°W which put it about 765 miles (1230 km) south of the southern tip of Baja California.  Eugene was moving toward the northwest at 8 m.p.h. (13 km/h).  The maximum sustained wind speed was 40 m.p.h. (65 km/h) and there were wind gusts to 50 m.p.h. (80 km/h).  The minimum surface pressure was 1006 mb.

The circulation of Tropical Storm Eugene is large and there are numerous bands of showers and thunderstorms rotating around the center of circulation.  A primary rainband is wrapping around the southern and eastern sides of the center and the strongest winds are occurring northeast of the center of circulation.  The circulation is circular and symmetrical.  Thunderstorms around the core of Eugene are beginning to generate upper level divergence which is pumping out mass in all directions.

Tropical Storm Eugene will move through an environment that is favorable for intensification.  Eugene will move over water where the Sea Surface Temperature is near 29°C.  The upper level winds over Tropical Storm Eugene are relatively weak and there is not a lot of vertical wind shear.  The circulation of Tropical Storm Eugene will continue to consolidate and it is likely to intensify during the weekend.  It is likely to become a hurricane and it could intensify rapidly if an eye forms.

Tropical Storm Eugene is moving near the western end of a subtropical ridge which is steering it toward the northwest.  A generally northwesterly motion is expected to continue during the next few days.  On its anticipated track Tropical Storm Eugene would move parallel to the west coast of Baja California and the center would remain west of the coast.
