Tropical Storm Eta Drops Heavy Rain on Nicaragua and Honduras

Tropical Storm Eta dropped heavy rain on Nicaragua and Honduras on Wednesday afternoon. At 4:00 p.m. EST on Wednesday the center of Tropical Storm Eta was located at latitude 13.9°N and longitude 85.7°W which put it about 100 miles (160 km) east of Tegucigalpa, Honduras. Eta was moving toward the west at 7 m.p.h. (11 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 999 mb.

The wind speeds in former Hurricane Eta decreased steadily on Wednesday as it move farther inland over northern Nicaragua. Eta weakened to a tropical storm, but the storm continued to drop heavy rain over parts of northern Nicaragua and Honduras. There were reports of flash floods in a number of locations. Thunderstorms in bands on the western and northern periphery of Tropical Storm Eta also dropped heavy rain over parts of Belize, Guatemala and Costa Rica. A strong rainband was also over the Caribbean Sea just east of Nicaragua.

Tropical Storm Eta will likely weaken to a tropical depression during Wednesday night. However, Eta will continue to drop locally heavy rain and more flash floods are likely to occur. Tropical Storm Eta will move around the southwestern part of a ridge of high pressure on Thursday. The high will steer Eta toward the west-northwest on Thursday. On its anticipated track Eta will move across Honduras to near the coast of Belize.

A upper level trough east of the Rocky Mountains is forecast to move southeast toward the Gulf of Mexico during the next several days. The southern end of the end of the trough will make a transition into a cutoff low. Counterclockwise circulation around the cutoff low will pull Eta toward the northeast on Friday. When Eta moves over the northwestern Caribbean Sea it will be in an environment somewhat favorable for intensification. Eta will move over water where the Sea Surface Temperature is near 29°C. The upper level trough will produce southwesterly winds which will blow toward the top of Eta’s circulation. Those winds will cause some vertical wind shear, but the shear may not be strong enough to prevent intensification. Eta could strengthen back into a tropical storm on Friday night. It is possible that Eta could develop the structure of a subtropical storm if the cutoff low causes enough wind shear to keep it from becoming a tropical storm again.

The counterclockwise rotation around the cutoff low will pull Eta more toward the north during the weekend. Eta is likely to move across Cuba and it could drop heavy rain when it does so. Eta will approach the Florida Keys on Sunday and it could bring gusty winds and locally heavy rain to the Keys and South Florida.

Major Hurricane Eta Makes Landfall in Nicaragua

Major Hurricane Eta made landfall on the coast of Nicaragua on Tuesday afternoon. At 4:00 p.m. EST on Tuesday the center of Hurricane Eta was located at latitude 13.8°N and longitude 83.5°W which put it about 15 miles (25 km) south-southwest of Puerto Cabezas, Nicaragua. Eta was moving toward the west at 5 m.p.h. (8 km/h). The maximum sustained wind speed was 140 m.p.h. (220 km/h) and there were wind gusts to 165 m.p.h. (265 km/h). The minimum surface pressure was 940 mb.

A Hurricane Warning was in effect for the portion of the coast from Sandy Bay Sirpi, Nicaragua to the Honduras/Nicaragua border. A Tropical Storm Warning was in effect for the portion of the coast from the Honduras/Nicaragua border to Punta Patuca, Honduras.

Hurricane Eta moved very slowly onto the coast of Nicaragua just to south of Puerto Cabezas on Tuesday afternoon. Concentric eyewalls developed around the center of Eta before it made landfall. The start of an eyewall replacement cycle caused the intensity of Hurricane Eta to remain relatively steady as it approached the coast of Nicaragua. An environment favorable for strong hurricanes allowed Eta to continue to be a major hurricane at the time of landfall.

Winds to hurricane force extended out 25 miles (40 km) from the center of Hurricane Eta at the time it made landfall. Winds to tropical storm force extended out 100 miles (160 km) from the center of circulation. The Hurricane Intensity Index (HII) for Hurricane Eta was 28.3. The Hurricane Size Index (HSI) was 9.4 and the Hurricane Wind Intensity Size Index (HWISI) was 37.7.

Hurricane Eta was capable of causing significant wind damage. over northeastern Nicaragua. The northern eyewall which contained the strongest winds passed over Puerto Cabezas. Eta could also cause a storm surge of 15 to 18 feet (5 to 6 meters) along the coast near Puerto Cabezas. Hurricane Eta will weaken as it moves slowly inland over northern Nicaragua and the wind speeds will decrease quickly. Eta will drop very heavy rain over northern Nicaragua and Honduras. Some locations could receive 20 to 30 inches (50 to 75 cm). The heavy rain could cause catastrophic flash floods in parts of Nicaragua and Honduras.

Eta will move more toward the northwest on Wednesday and the circulation could emerge over the northwestern Caribbean Sea on Friday. There is a chance that Eta could strengthen back to a tropical storm if the circulation moves back over water. Eta could bring gusty winds and rain to the Florida Keys by Sunday.

Hurricane Eta Rapidly Intensifies to a Major Hurricane

Hurricane Eta rapidly intensified to a major hurricane over the Caribbean Sea east of Nicaragua on Monday afternoon. At 1:00 p.m. EST on Monday the center of Hurricane Eta was located at latitude 14.7°N and longitude 82.0°W which put it about 85 miles (135 km) east of Cabo Gracias a Dios. Eta was moving toward the west at 10 m.p.h. (16 km/h). The maximum sustained wind speed was 120 m.p.h. (195 km/h) and there were wind gusts to 140 m.p.h. (225 km/h). The minimum surface pressure was 957 mb.

A Hurricane Warning was in effect for the portion of the coast from Sandy Bay Sirpi, Nicaragua to the Honduras/Nicaragua border. A Hurricane Watch was in effect for the portion of the coast from the Honduras/Nicaragua border to Punta Patuca, Honduras. A Tropical Storm Warning was in effect for the portion of the coast from the Honduras/Nicaragua border to Punta Patuca, Honduras. A Tropical Storm Watch was in effect for the portion of the coast from Punta Patuca to Punta Castilla, Honduras.

Hurricane Eta continued to intensify rapidly on Monday afternoon. A small circular eye with a diameter of 12 miles (19 km) developed at the center of Hurricane Eta. The eye was surrounded by a ring of strong thunderstorms and the strongest winds were occurring in that ring of storms. Thunderstorms near the center of Eta generated strong upper level divergence which pumped mass away from the tropical storm. The removal of mass allowed the surface pressure to decrease quickly, which contributed to rapid intensification. Bands of showers and thunderstorms were revolving around the core of Hurricane Eta.

Winds to hurricane force extended out 25 miles (40 km) from the center of circulation. Winds to tropical storm force extended out 120 miles (195 km) from the center. The Hurricane Intensity Index (HII) for Hurricane Eta was 22.1. The Hurricane Size Index (HSI) was 7.6 and the Hurricane Wind Intensity Size Index (HWISI) was 29.7. Hurricane Eta was capable of causing major damage.

Hurricane Eta will move through an environment favorable for intensification during the next 9 hours. Eta will move over water where the Sea Surface Temperature is near 29°C. It will move through a region where the upper level winds are weak and there will be little vertical wind shear. Hurricane Eta is likely to continue to intensify rapidly during the next few hours and it could strengthen to Category 4 on the Saffir-Simpson Scale.

Hurricane Eta will move south of a ridge of high pressure over the western Atlantic Ocean. The ridge will steer Eta toward the west during the next 24 to 36 hours. On its anticipated path Hurricane Eta could approach the coast of Nicaragua on Tuesday morning. Eta will be a major hurricane when it reaches Nicaragua. The steering currents will weaken when Hurricane Eta nears Nicaragua. Eta will move slowly when that happens and it could drop very heavy rain over Nicaragua and Honduras. Catastrophic flash floods could occur in that region.

A Tropical Storm Watch was in effect for the portion of the coast from Punta Patuca to Punta Castilla, Honduras.

A U.S. Air Force Reserve Hurricane Hunter aircraft found that Hurricane Eta was intensifying rapidly on Monday morning. A small circular eye with a diameter of 12 miles (19 km) developed at the center of Hurricane Eta. The eye was surrounded by a ring of strong thunderstorms and the strongest winds were occurring in that ring of storms. Thunderstorms near the center of Eta generated strong upper level divergence which pumped mass away from the tropical storm. The removal of mass allowed the surface pressure to decrease quickly , which contributed to rapid intensification. Bands of showers and thunderstorms were revolving around the core of Hurricane Eta. Winds to hurricane force extended out 25 miles (40 km) from the center of circulation. Winds to tropical storm force extended out 130 miles (210 km) from the center.

Hurricane Eta will move through an environment favorable for intensification during the next 12 hours. Eta will move over water where the Sea Surface Temperature is near 29°C. It will move through a region where the upper level winds are weak and there will be little vertical wind shear. Hurricane Eta is likely to continue to intensify rapidly during the next few hours and it could strengthen into a major hurricane.

Hurricane Eta will move south of a ridge of high pressure over the western Atlantic Ocean. The ridge will steer Eta toward the west during the next 24 to 48 hours. On its anticipated path Tropical Storm Eta could approach the coast of Nicaragua on Monday night. Eta could be a major hurricane when it reaches Nicaragua. The steering currents will weaken when Eta nears Nicaragua. Eta will move slowly when that happens and it could drop very heavy rain over Nicaragua and Honduras.

A NOAA aircraft found that Tropical Storm Eta had strengthened on Sunday afternoon. Thunderstorms near the center of Eta generated upper level divergence which pumped mass away from the tropical storm. The removal of mass allowed the surface pressure to decrease, which contributed to an increase in the wind speed. Bands of showers and thunderstorms were revolving around the core of Tropical Storm Eta. Winds to tropical storm force extended out 140 miles (220 km) from the center of the tropical storm.

Tropical Storm Eta will move through an environment favorable for intensification during the next 24 hours. Eta will move over water where the Sea Surface Temperature is near 29°C. It will move through a region where the upper level winds are weak and there will be little vertical wind shear. Tropical Storm Eta could intensify into a hurricane within 12 hours. Eta could intensify rapidly once an inner core if fully developed. There is a chance that Eta could strengthen into a major hurricane.

Tropical Storm Eta will move south of a ridge of high pressure over the western Atlantic Ocean. The ridge will steer Eta toward the west during the next couple of days. On its anticipated path Tropical Storm Eta could approach the coast of Nicaragua on Monday night. Eta could be a major hurricane when it reaches Nicaragua. The steering currents will weaken when Eta nears Nicaragua. Eta will move slowly when that happens and it could drop very heavy rain over Nicaragua and Honduras. Catastrophic flash floods could occur in that region.

TD 29 Strengthens to Tropical Storm Eta, Hurricane Watches for Nicaragua and Honduras

Former Tropical Depression Twentynine strengthened into Tropical Storm Eta over the central Caribbean Sea on Saturday night and Hurricane Watches were issued for Nicaragua and Honduras. At 11:00 p.m. EDT on Saturday the center of Tropical Storm Eta was located at latitude 15.0°N and longitude 74.2°W which put it about 600 miles (965 km) east of Cabo Gracias a Dios. Eta was moving toward the west at 15 m.p.h. (24 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.

A Hurricane Watch was issued for the portion of the coast from Puerto Cabezas, Nicaragua to Punta Patuca, Honduras.

The circulation around former Tropical Depression Twentynine exhibited greater organization on Saturday night and the National Hurricane Center upgraded the system to Tropical Storm Eta. The inner part of a rainband wrapped partly around the eastern side of the center of circulation. Other bands of showers and thunderstorms were revolving around the center. Storms near the center generated upper level divergence which pumped mass away from the tropical storm. Winds to tropical storm force extended out 50 miles (80 km) on the northern side of Tropical Storm Eta. The winds in the southern half of Eta were blowing at less than tropical storm force.

Tropical Storm Eta will move through an environment favorable for intensification during the next 48 hours. Eta will move over water where the Sea Surface Temperature is near 29°C. It will move through a region where the upper level winds are weak and there will be little vertical wind shear. Tropical Storm Eta could intensify into a hurricane within 48 hours.

Tropical Storm Eta will move south of a ridge of high pressure over the western Atlantic Ocean. The ridge will steer Eta toward the west during the next couple of days. On its anticipated path Tropical Storm Eta could approach Nicaragua and Honduras in 48 hours. Eta could be a hurricane when it gets there.
