Hurricane Grace Hits Yucatan

Hurricane Grace hit the Yucatan Peninsula on Thursday morning. At 8:00 a.m. EDT on Thursday the center of Hurricane Grace was located at latitude 20.1°N and longitude 87.9°W which put it about 45 miles (65 km) south-southeast of Valladolid, Mexico. Grace was moving toward the west at 17 m.p.h. (28 km/h). The maximum sustained wind speed was 75 m.p.h. (120 km/h) and there were wind gusts to 90 m.p.h. (145 km/h). The minimum surface pressure was 989 mb.

A Hurricane Warning was in effect for the portion of the coast from Cancun to Punta Herrero, Mexico. The Hurricane Warning included Cozumel. A Hurricane Watch was in effect for the portion of the coast from Puerto Veracruz to Cabo Rojo,, Mexico. Tropical Storm Warnings were in effect for the portions of the coast from Cancun to Campeche, Mexico and from Punta Herrero to Puerto Costa Maya, Mexico. A Tropical Storm Watch was in effect for the portion of the coast from Cabo Rojo to Puerto de Altamira, Mexico. Tropical Storm Watches were also in effect for the Cuban provinces of Isla de la Juventud and Pinar del Rio.

The center of Hurricane Grace made landfall on the east coast of the Yucatan Peninsula southeast of Tulum on Thursday morning. The maximum sustained wind speed was 80 m.p.h. (130 km/h) at the time of landfall. Winds to hurricane force extended out 35 miles (55 km) from the center of Hurricane Grace. Winds to tropical storm force extended out 140 miles (220 km) from the center of circulation. Grace will produce strong gusty winds over the Yucatan. It will also drop heavy rain and flash floods are likely to occur. Hurricane Grace will weaken gradually back to a tropical storm while it moves across the Yucatan.

Hurricane Grace will move over the southwestern Gulf of Mexico on Thursday night. Grace will move into an environment favorable for intensification when it moves over the Gulf of Mexico. Grace will move over water where the Sea Surface Temperatures are near 30°C. It will move into a region where the upper level winds are weak and there will be little vertical wind shear. Grace is likely to intensify back to a hurricane on Friday.

Hurricane Grace will move south of a subtropical high pressure system that extends over the Gulf of Mexico. The high will steer Grace toward the west during the next several days. On its anticipated track Hurricane Grace will move across the Yucatan Peninsula on Thursday. Grace will move over the southwestern Gulf of Mexico on Thursday night. Hurricane Grace could approach the coast of Mexico between Veracruz and Tampico on Friday night.

Elsewhere, former Tropical Storm Fred was dropping heavy rain over parts of the northeastern U.S. and Tropical Storm Henri was moving west toward the east coast of the U.S.

At 5:00 a.m. EDT on Thursday the center of former Tropical Storm Fred was located at latitude 42.0°N and longitude 76.0°W which put it about 15 miles (25 km) south of Binghamton, New York. Fred was moving toward the east-northeast at 17 m.p.h. (28 km/h). The maximum sustained wind speed was 25 m.p.h. (40 km/h) and there were wind gusts to 35 m.p.h. (55 km/h). The minimum surface pressure was 1011 mb. Flood Watches and Flash Flood Watches were in effect for parts of the northeastern U.S.

At 5:00 a.m. EDT on Thursday the center of Tropical Storm Henri was located at latitude 29.5°N and longitude 69.5°W which put it about 525 miles (845 km) southeast of Cape Hatteras, North Carolina. Henri was moving toward the west at 9 m.p.h. (15 km/h). The maximum sustained wind speed was 70 m.p.h. (110 km/h) and there were wind gusts to 85 m.p.h. (135 km/h). The minimum surface pressure was 995 mb.

TD 22 Forms over Western Gulf of Mexico, Teddy at Cat. 4

Tropical Depression Twentytwo formed over the western Gulf of Mexico on Thursday evening and Hurricane Teddy intensified to Category 4 on the Saffir-Simpson Scale.  At 11:00 p.m. EDT on Thursday the center of Tropical Depression Twentytwo was located at latitude 22.0°N and longitude 94.2°W which put it about 235 miles (380 km) east of Tampico, Mexico.  The depression was moving toward the northeast at 3 m.p.h. (5 km/h).  The maximum sustained wind speed was 35 m.p.h. (55 km/h) and there were wind gusts to 45 m.p.h. (75 km/h).  The minimum surface pressure was 1005 mb.

An Air Force Reserve Hurricane Hunter plane determined that a low level center of circulation was present in a low pressure system over the western Gulf of Mexico on Thursday evening and the National Hurricane Center designated the system as Tropical Depression Twentytwo.  The circulation around the depression was still organizing.  Bands of showers and thunderstorms were developing.  Storms near the center of circulation began to generate upper level divergence which pumped mass away from the tropical depression.

Tropical Depression Twentytwo will move through an environment favorable for intensification during the next several days.  The depression will move over water where the Sea Surface Temperature is near 30°C.  An upper level low near the Rio Grande Valley will produce southerly winds which will blow toward the top of the depression.  Those winds will cause some vertical wind shear.  The shear will inhibit intensification, but the depression is likely to strengthen into a tropical storm.

Tropical Depression Twentytwo will be in an area where the steering currents are weak.  The upper low over the Rio Grande Valley could pull the depression toward the north, but the depression could meander over the western Gulf of Mexico for several days.

Elsewhere, Hurricane Teddy strengthened to Category 4 on the Saffir-Simpson Scale southeast of Bermuda on Thursday evening.  At 11:00 p.m. EDT on Thursday the center of Hurricane Teddy was located at latitude 20.9°N and longitude 54.7°W which put it about 1005 miles (1615 km) southeast of Bermuda.  Teddy was moving toward the northwest at 12 m.p.h. (19 km/h).  The maximum sustained wind speed was 140 m.p.h. (220 km/h) and there were wind gusts to 170 m.p.h. (280 km/h).  The minimum surface pressure was 945 mb.  On its anticipated track Hurricane Teddy could be near Bermuda by Sunday night.
