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.

Hurricane Eta Rapidly Intensifies

Hurricane Storm Eta rapidly intensified over the Caribbean Sea east of Nicaragua on Monday afternoon. At 7:00 a.m. EST on Monday the center of Hurricane Eta was located at latitude 14.8°N and longitude 81.1°W which put it about 140 miles (225 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 90 m.p.h. (145 km/h) and there were wind gusts to 110 m.p.h. (175 km/h). The minimum surface pressure was 974 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.

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. Catastrophic flash floods could occur in that region.
