Tropical Storm Gamma emerged over the southern Gulf of Mexico on Sunday.  At 2:00 p.m. EDT on Sunday the center of Tropical Storm Gamma was located at latitude 22.4°N and longitude 88.0°W which put it about 120 miles (195 km) east-northeast of Progreso, Mexico.  Gamma was moving toward the north at 2 m.p.h. (3 km/h).  The maximum sustained wind speed was 60 m.p.h. (95 km/h) and there were wind gusts to 75 m.p.h. (120 km/h).  The minimum surface pressure was 997 mb.

A Tropical Storm Warning was in effect from Cancun to Dzilam, Mexico.  A Tropical Storm Watch was in effect from Dzilam to Progreso, Mexico.

Tropical Storm Gamma emerged over the Gulf of Mexico north of the Yucatan Peninsula on Sunday.  The circulation around Gamma was relatively intact after its passage over the northeastern Yucatan Peninsula.  Thunderstorms persisted near the center of circulation.  Bands of showers and thunderstorms were revolving around the center of Tropical Storm Gamma.  Storms near the center generated upper level divergence which pumped mass away to the north of the tropical storm.  Winds to tropical storm force extended out 115 miles (185 km) from the center of Gamma.

Tropical Storm Gamma will be in an environment that will become less favorable for intensification.  Gamma will be over water where the Sea Surface Temperature is 30°C.  So, there will be sufficient energy to support intensification.  However, Tropical Storm Gamma will be under the western end of an upper level ridge centered over the Bahamas.  The ridge will produce southerly winds which will blow toward the top of Gamma.  Those winds will cause moderate vertical wind shear and they could be strong enough to blow the upper part of Gamma north of the circulation in the lower levels.

Northward movement of Tropical Storm Gamma is likely to be blocked by a ridge which will form in the middle troposphere over the northern Gulf  of Mexico.  After it forms, that ridge is likely to steer Gamma slowly toward the west or west-southwest.  On its anticipated track Tropical Storm Gamma will move slowly toward the west-southwest and it will remain just north of the Yucatan Peninsula.
