Tropical Storm Nana Moves Over Guatemala

Tropical Storm Nana moved over Guatemala on Thursday.  At 2:00 p.m. EDT on Thursday the center of Tropical Storm Nana was located at latitude 16.3°N and longitude 90.6°W which put it about 120 miles (195 km) north of Guatemala City, Guatemala.  Nana was moving toward the west t 14 m.p.h. (22 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 1005 mb.

After making landfall in southern Belize as a hurricane on Wednesday night, Tropical Storm Nana moved westward over northern Guatemala.  The small circulation around Nana weakened steadily on Thursday.  Tropical Storm Nana was dropping locally heavy rain over Guatemala on Thursday afternoon.  The heavy rain could cause flash floods in some locations.

Tropical Storm Nana will weaken to a tropical depression within a few hours.  Nana will continue to move toward the west.  It could emerge over the Gulf of Tehuantepec on Friday.

Elsewhere over the Atlantic Ocean, Tropical Depression Omar moved away from Bermuda.  At 11:00 a.m. EDT on Thursday the center of Tropical Depression Omar was located at latitude 35.9°N and longitude 61.1°W which put it about 335 miles (540 km) northeast of Bermuda.  Omar was moving toward the east at 13 m.p.h. (20 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.

Nana Strengthens to a Hurricane Near Belize

Former Tropical Storm Nana strengthened into a hurricane as it neared a landfall in Belize.  At 11:00 p.m. EDT on Wednesday the center of Hurricane Nana was located at latitude 17.0°N and longitude 87.5°W which put it about 60 miles (95 km) southeast of Belize City, Belize.  Nana was moving toward the west at 16 m.p.h. (26 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 994 mb.

A Hurricane Warning was in effect for the portion of the coast from Belize City to the Belize/Guatemala border.  A Hurricane Watch was in effect for the portion of the coast from Belize City to the Belize/Mexico border.  A Tropical Storm Warning was in effect for the portion of the coast from Belize City to Belize/Mexico border.  A Hurricane Warning was also in effect for the portion of the coast from Puerto Costa Maya to Chetumal, Mexico.  Tropical Storm Warnings were in effect for the Caribbean Sea coast of Guatemala, Isla Roatan and the Bay Islands.  A Tropical Storm Watch was in effect for the north coast of Honduras from Punta Patuca to the border with Guatemala.

Former Tropical Storm Nana moved into a more favorable environment on Wednesday night and strengthened to a hurricane.  More thunderstorms formed near the center of circulation and those thunderstorms helped to spin up the circulation.  Since the circulation around Hurricane Nana was relatively small, it was able to spin up into a hurricane in a few hours.  Winds to hurricane force extended out 15 miles (25 km) on the northern side of Nana.  Winds to tropical storm force only extended out 70 miles (110 km) from the center of circulation.

Hurricane Nana has a few more hours when it could strengthen before it makes landfall in southern Belize.  Nana will move over water where the Sea Surface Temperature is near 30°C.  It will move through a region where the upper level winds are weak and there will be less vertical wind shear.  Hurricane Nana could get a little stronger.

Hurricane Nana will move south of a subtropical high pressure system over the western Atlantic Ocean.  The high will steer Nana a little to the south of due west.  On its anticipated track Hurricane Nana will make landfall on the coast of Belize south of Belize City early on Wednesday morning.  Nana will be capable of causing localized wind damage.  It could cause a storm surge of up to eight feet (2.6 meters) along the south coast of Belize.  Hurricane Nana will drop heavy rain over parts of southern Belize and northern Guatemala.  Flash floods could occur in some locations.

Elsewhere over the North Atlantic Ocean, former Tropical Storm Omar weakened to a tropical depression north of Bermuda.  At 11:00 p.m. EDT on Wednesday the center of Tropical Depression Omar was located at latitude 36.1°N and longitude 64.1°W which put it about 265 miles (425 km) north of Bermuda.  Omar was moving toward the east at 13 m.p.h. (20 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.

Tropical Storm Nana Strengthens, Hurricane Watch Issued for Belize

Tropical Storm Nana strengthened on Tuesday night and a Hurricane Watch was issued for Belize.  At 11:00 p.m. EDT on Tuesday the center of Tropical Storm Nana was located at latitude 17.0°N and longitude 80.9°W which put it about 485 miles (775 km) east of Belize City, Belize.  Nana was moving toward the west at 18 m.p.h. (30 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 999 mb.

A Hurricane Watch was issued for the entire coast of Belize.  A Tropical Storm Warning was also in effect for Belize.  A Tropical Storm Warning was in effect for the portion of the coast from Puerto Costa Maya to Chetumal, Mexico.  Tropical Storm Watches were in effect for the Caribbean Sea coast of Guatemala and for the north coast of Honduras from Punta Patuca to the border with Guatemala including Roatan Island and the Bay Islands.

Tropical Storm Nana continued to strengthen on Tuesday night.  There were signs that a small eye might be starting to form in the lower levels of the atmosphere.  More thunderstorms formed near the center of circulation.  Storms near the center generated upper level divergence which pumped mass away from the tropical storm.  Winds to tropical storm force extended out 80 miles (130 km) from the center of circulation.

Tropical Storm Nana will move through an environment favorable for intensification during the next 24 hours.  Nana will move over water where the Sea Surface Temperature is near 29.5°C.  It will move through a region where the upper level winds are weak and there will be little vertical wind shear.  Tropical Storm Nana is likely to intensify into a hurricane on Wednesday.

Tropical Storm Nana will move south of a subtropical high pressure system over the Atlantic Ocean.  The high will steer Nana toward the west during the next 24 to 36 hours.  On its anticipated track the center of Tropical Storm Nana will pass north of Honduras.  Nana could approach Belize on Wednesday night.

Elsewhere over the Atlantic Ocean, Tropical Storm Omar continued to move away from North Carolina.  At 11:00 p.m. EDT on Tuesday the center of Tropical Storm Omar was located at latitude 35.8°N and longitude 70.0°W which put it about 310 miles (500 km) east of Cape Hatteras, North Carolina.  Omar was moving toward the east-northeast at 14 m.p.h. (22 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 1003 mb.

Tropical Storm Nana Forms South of Jamaica

Tropical Storm Nana formed over the Caribbean Sea south of Jamaica on Tuesday.  At 2:00 p.m. EDT on Tuesday the center of Tropical Storm Nana was located at latitude 16.7°N and longitude 78.4°W which put it about 110 miles (175 km) south of Negril, Jamaica.  Nana was moving toward the west at 18 m.p.h. (30 km/h).  The maximum sustained wind speed was 50 m.p.h. (80 km/h) and there were wind gusts to 65 m.p.h. (105 km/h).  The minimum surface pressure was 1002 mb.

A Tropical Storm Watch was issued for the entire coast of Belize.  A Tropical Storm Watch was also issued for the north coast of Honduras from Punta Patuca to the border with Guatemala including Roatan Island and the Bay Islands.

An Air Force Reserve Hurricane Hunter flight into a low pressure system south of Jamaica found a defined low level center of circulation and winds to tropical storm force on Tuesday.  Based on data from the reconnaissance aircraft the National Hurricane Center designated the system Tropical Storm Nana.  The circulation around Tropical Storm Nana was organizing quickly.  Thunderstorms were developing near the center of circulation.  Bands of showers and thunderstorms were revolving around the center.  Storms near the center began to generate upper level divergence which was pumping mass away from the tropical storm.  The strongest winds were occurring in the northern half of the circulation.  Winds to tropical storm force extended out 80 miles (130 km) from the center of Nana.

Tropical Storm Nana will move through an environment favorable for intensification during the next 36 hours.  Nana will move over water where the Sea Surface Temperature is near 29.5°C.  It will move through a region where the upper level winds are weak and there will be little vertical wind shear.  Tropical Storm Nana will continue to intensify and it is likely to strengthen to a hurricane within 36 hours.

Tropical Storm Nana will move south of a subtropical high pressure system over the Atlantic Ocean.  The high will steer Nana toward the west during the next day or two.  On its anticipated track the center of Tropical Storm Nana will pass north of Honduras on Wednesday.  Nana could reach Belize on Thursday and it is likely to be a hurricane by that time.

Elsewhere over the Atlantic Ocean, Tropical Depression Fifteen moved away from the East Coast of the U.S.  At 11:00 a.m. EDT on Tuesday the center of Tropical Depression Fifteen was located at latitude 34.7°N and longitude 73.1°W which put it about 140 miles (225 km) east-southeast of Cape Hatteras, North Carolina.  The depression was moving toward the east-northeast at 14 m.p.h. (22 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 1008 mb.
