Hurricane Iota Drops Heavy Rain over Nicaragua and Honduras

Hurricane Iota was dropping heavy rain over Nicaragua and Honduras on Tuesday morning. At 10:00 a.m. EST on Tuesday the center of Hurricane Iota was located at latitude 13.7°N and longitude 85.2°W which put it about 135 miles (220 km) east of Tegucigapla, Honduras. Iota was moving toward the west at 12 m.p.h. (19 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 980 mb.

A Tropical Storm Warning was in effect for the portion of the coast from Bluefields, Nicaragua to the Honduras/Guatemala border including the Bay Islands.

Hurricane Iota continued to move steadily inland over Nicaragua on Tuesday morning. The center of Iota was just to the east of the border between Nicaragua and Honduras. Hurricane Iota was dropping heavy rain over much of Nicaragua and Honduras. Bands of showers and thunderstorms continued to revolve around the center of Iota. Those rainbands were dropping rain fast enough to cause flash floods over many of the same places that were flooded by Hurricane Eta.

Hurricane Iota will continue to move westward during the next 24 to 36 hours. Iota will weaken to a tropical storm when its center moves over Honduras during the next few hours. Iota will likely be a tropical depression when the center reaches El Salvador on Tuesday night. Even though Hurricane Iota will weaken steadily, it will continue to drop heavy rain over Nicaragua, Honduras and El Salvador. Catastrophic flash floods could occur in that region.

Dangerous Hurricane Iota Hits Nicaragua

Dangerous Hurricane Iota hit Nicaragua with powerful winds and heavy rain on Monday night. At 10:00 p.m. EST on Monday the center of Hurricane Iota was located at latitude 13.6°N and longitude 83.4°W which put it about 30 miles (50 km) south of Puerto Cabezas, Nicaragua. Iota was moving toward the west at 9 m.p.h. (15 km/h). The maximum sustained wind speed was 155 m.p.h. (250 km/h) and there were wind gusts to 185 m.p.h. (300 km/h). The minimum surface pressure was 920 mb.

A Hurricane Warning was in effect for the portion of the coast from Sandy Bay Sirpi, Nicaragua to Punta Patuca, Honduras. Tropical Storm Warnings were in effect for the portions of the coast from Bluefields to Sandy Bay Sirpi, Nicaragua and from Punta Patuca to the Honduras/Guatemala border including the Bay Islands. Tropical Storm Warnings were also in effect for San Andres and Providencia Island.

Hurricane Iota was a powerful hurricane when it made landfall on the coast of Nicaragua just to the south of Puerto Cabezas. Iota was at Category 4 on the Saffir-Simpson Scale. Winds to hurricane force extended out 45 miles (75 km) from the center of circulation. Winds to tropical storm force extended out 175 miles (280 km) from the center, The Hurricane Intensity Index (HII) for Hurricane Iota was 33.3. The Hurricane Size Index (HSI) was 16.3 and the Hurricane Wind Intensity Size Index (HWISI) was 49.6. Iota was capable of causing regional significant damage.

Hurricane Iota made landfall on the same portion of the coast of Nicaragua devastated by Hurricane Eta two weeks ago. Iota will compound the damage caused by Eta. Strong winds will cause additional damage and they will destroy temporary shelters erected after Hurricane Eta. The winds blowing water toward the coast could cause a storm surge of up to 20 feet (6 meters) south of Puerto Cabezas.

Hurricane Iota will continue to move toward the west during the next 48 hours. On its anticipated track the center of Iota will move across northern Nicaragua, southern Honduras and El Salvador. The winds around Hurricane Iota will weaken steadily as it moves inland. Iota will drop heavy rain over Nicaragua, Honduras, and El Salvador. The heavy rain will cause flash floods and some floods will occur in the same locations flooded by Hurricane Eta.

Hurricane Iota Rapidly Intensifies to Cat. 5

Hurricane Iota rapidly intensified to Category 5 on the Saffir-Simpson Scale on Monday morning. At 10:00 a.m. EST on Monday the center of Hurricane Iota was located at latitude 13.5°N and longitude 82.0°W which put it about 100 miles (160 km) east-southeast of Cabo Gracias a Dios. Iota was moving toward the west at 9 m.p.h. (15 km/h). The maximum sustained wind speed was 160 m.p.h. (260 km/h) and there were wind gusts to 190 m.p.h. (305 km/h). The minimum surface pressure was 917 mb.

A Hurricane Warning was in effect for the portion of the coast from Sandy Bay Sirpi, Nicaragua to Punta Patuca, Honduras and for Providencia Island. A Hurricane Watch was in effect for San Andres. Tropical Storm Warnings were in effect for the portions of the coast from Bluefields to Sandy Bay Sirpi, Nicaragua and from Punta Patuca to the Honduras/Guatemala border including the Bay Islands. A Tropical Storm Warning was also in effect for San Andres.

Hurricane Iota intensified very rapidly on Sunday night and it reached Category 5 on the Saffir-Simpson Scale on Monday morning. A reconnaissance aircraft found a circular eye with a diameter of 14 miles (22 km) at the center of Iota. The eye was surrounded by a ring of strong thunderstorms and the strongest winds were occurring in that ring of storms. Bands of showers and thunderstorms were revolving around the core of Hurricane Iota. Storms near the core generated strong upper level divergence which pumped mass away from the hurricane in all directions. The removal of large quantities of mass allowed the surface pressure to decrease rapidly which produced the very rapid intensification.

Winds to hurricane force extended out 35 miles (55 km) from the center of Hurricane Iota. Winds to tropical storm force extended out 150 miles (240 km) from the center. The Hurricane Intensity Index (HII) for Hurricane Iota was 35.0. The Hurricane Size Index (HSI) was 13.9 and the Hurricane Wind Intensity Size Index (HWISI) was 48.9. Hurricane Iota was capable of causing catastrophic damage.

Hurricane Iota will move through an capable of supporting a very intense hurricane on Monday. Iota 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. If the inner end of a rainband wraps around the existing eye and eyewall, then an eyewall replacement cycle could begin. An eyewall replacement cycle could cause Hurricane Iota to start to weaken, but Iota could still be at Category 5 when it makes landfall on the northern coast of Nicaragua.

Hurricane Iota will move south of a high pressure system over the western Atlantic Ocean. The high will steer Iota toward the west during the next several days. On its anticipated track Iota could approach the coast a little to the south of the border between Nicaragua and Honduras on Monday night. Hurricane Iota will be a major hurricane when it reaches the coast and it could be at Category 5. Nicaragua and Honduras are still trying to cope with floods and other damage caused by Hurricane Eta. Another major hurricane could have catastrophic consequences for that region.

Hurricane Iota Rapidly Intensifies East of Nicaragua

Hurricane Iota rapidly intensified east of Nicaragua on Sunday morning. At 10:00 a.m. EST on Sunday the center of Hurricane Iota was located at latitude 13.2°N and longitude 77.8°W which put it about 380 miles (615 km) east-southeast of Cabo Gracias a Dios. Iota was moving toward the west-northwest at 6 m.p.h. (10 km/h). The maximum sustained wind speed was 85 m.p.h. (135 km/h) and there were wind gusts to 100 m.p.h. (160 km/h). The minimum surface pressure was 982 mb.

A Hurricane Warning was in effect for the portion of the coast from Sandy Bay Sirpi, Nicaragua to Punta Patuca, Honduras and for Providencia Island. A Hurricane Watch was in effect for San Andres. Tropical Storm Warnings were in effect for the portions of the coast from Bluefields to Sandy Bay Sirpi, Nicaragua and from Punta Patuca to Punta Castilla, Honduras. A Tropical Storm Warning was also in effect for San Andres.

Hurricane Iota was intensifying rapidly on Sunday morning. A small eye formed at the center of Iota. The eye was surrounded by a ring of strong thunderstorms and the strongest winds were occurring in that ring of storms. Bands of showers and thunderstorms were revolving around the core of Hurricane Iota. Storms near the core generated strong upper level divergence which pumped mass away from the hurricane. The removal of mass caused the surface pressure to decrease quickly, which contributed to the rapid intensification. Winds to hurricane force extended out 30 miles from the center of circulation. Winds to tropical storm force extended out 90 miles from the center.

Hurricane Iota will move through an environment very favorable for intensification during the next 36 hours. Iota 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 Iota is likely to continue to intensify rapidly. Iota could strengthen into a major hurricane within 24 hours and it could intensify to Category 4 on the Saffir-Simpson Scale.

Hurricane Iota will move south of a high pressure system over the western Atlantic Ocean. The high will steer Iota toward the west during the next several days. On its anticipated track Iota could approach the coast near the border between Nicaragua and Honduras on Monday night. Hurricane Iota is likely be a major hurricane when it reaches the coast. Nicaragua and Honduras are still trying to cope with floods and other damage caused by Hurricane Eta a few days ago. Another major hurricane could have catastrophic consequences for that region.

Elsewhere over the Atlantic Ocean, former Tropical Storm Theta weakened to a tropical depression southwest of Madeira. At 7:00 a.m. EST on Sunday the center of Tropical Depression Theta was located at latitude 31.8°N and longitude 18.3°W which put it about 120 miles (195 km) southwest of Madeira. Theta was moving toward the east 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 1003 mb.
