Tropical Cyclone Freddy Drops Heavy Rain on Mozambique

Tropical Cyclone Freddy dropped heavy rain on parts of Mozambique on Sunday. At 8:00 a.m. EDT on Sunday the center of Tropical Cyclone Freddy was located at latitude 17.2°S and longitude 36.3°E which put it about 55 miles (90 km) northwest of Quelimane, Mozambique. Freddy was moving toward the west-northwest at 6 m.p.h. (9 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 996 mb.

Tropical Cyclone Freddy dropped heavy rain on parts of Mozambique and eastern Zimbabwe on Sunday as it moved slowly farther inland. Since Freddy was moving slowly, there were prolonged periods of heavy rain in some locations. The prolonged periods of heavy rain caused a high risk for floods in those locations. Tropical Cyclone Freddy was still producing winds to tropical storm force in the bands in the eastern side of the circulation over the Mozambique Channel.

Tropical Cyclone Freddy will be in an area where the steering winds are weak during the next several days. Freddy’s circulation is forecast to meander over Mozambique and eastern Zimbabwe. Tropical Cyclone Freddy will continue to weaken slowly while the center of circulation is over land. Freddy will continue to drop heavy rain over parts of Mozambique and eastern Zimbabwe for the next 48 hours. Additional flooding is likely to occur in those places that receive prolonged heavy rain.

Tropical Cyclone Ana Brings Wind and Rain to Northern Mozambique

Tropical Cyclone Ana brought wind and rain to northern Mozambique on Monday morning. At 7:00 a.m. EST on Monday the center of Tropical Cyclone Ana was located at latitude 16.4°S and longitude 38.6°E which put it about 35 miles (55 km) west of Moma, Mozambique. Ana was moving toward the west at 21 m.p.h. (33 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 992 mb.

The center of Tropical Cyclone Ana made landfall on the coast of northern Mozambique between Angoche and Moma on Monday morning. Ana was the equivalent of a tropical storm at the time of landfall. Winds to tropical storm force extended out 160 miles (260 km) in the eastern side of Ana’s circulation. The strongest winds were occurring over the Mozambique Channel. The winds were weaker over land. Thunderstorms in bands in the western half of Tropical Cyclone Ana were dropping heavy rain over parts of northern Mozambique.

Tropical Cyclone Ana will move around the northern side of a high pressure system over the Southwest Indian Ocean. The high pressure system will steer Ana toward the west during the next 36 hours. On its anticipated track the center of Tropical Cyclone Ana will move across northern Mozambique and southern Malawi. The center of Ana could pass near Mualama, Mucubela, and Mocuba. Tropical Cyclone Ana will weaken gradually as it moves farther inland. Ana will bring gusty winds and locally heavy rain to northern Mozambique, southern Malawi and northern Zimbabwe. Heavy rain could cause flash floods in some locations. Weather conditions over the Mozambique Channel should improve slowly as Tropical Cyclone Ana moves farther inland.

Tropical Cyclone Ana Strengthens over Mozambique Channel

Tropical Cyclone Ana strengthened over the Mozambique Channel on Sunday. At 10:00 p.m. EST on Sunday the center of Tropical Cyclone Ana was located at latitude 15.8°S and longitude 41.5°E which put it about 110 miles (175 km) east-northeast of Angoche, Mozambique. Ana was moving toward the west at 14 m.p.h. (22 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 991 mb.

A former tropical depression strengthened to Tropical Cyclone Ana over the Mozambique Channel on Sunday. The inner end of a rainband wrapped around the northern side of the center of Ana’s circulation on Sunday evening. Other bands of showers and thunderstorms were revolving around the center of circulation. The strongest thunderstorms were occurring in bands in the northern and western parts of Ana. Bands in the southeastern part of the circulation consisted primarily of showers and lower clouds. The air in that part of Tropical Cyclone Ana had passed over Madagascar and may have been sinking. Storms near the center of Ana generated upper level divergence that pumped mass away to the west of the tropical cyclone. Winds to tropical storm force extended out 160 miles (260 km) from the center of circulation.

Tropical Cyclone Ana will move through an environment favorable for intensification for the next few hours. Ana will move over water where the Sea Surface Temperatures are near 30˚C. It will move under the northwestern part of an upper level ridge over the Southwest Indian Ocean. The ridge will produce easterly winds that will blow toward the top of the circulation. Those winds will cause some vertical wind shear, but the wind shear will not be strong enough to prevent intensification. Ana could get stronger before it reaches the coast of Mozambique on Monday.

Tropical Cyclone Ana will move around the northern side of a high pressure system over the Southwest Indian Ocean. The high pressure system will steer Ana toward the west during the next 36 hours. On its anticipated track the center of Tropical Cyclone Ana could make landfall on the coast of Mozambique near Angoche in a few hours. Ana will bring gusty winds and locally heavy rain to northern Mozambique, southern Malawi and northern Zimbabwe. Heavy rain could cause flash floods in some locations. Tropical Cyclone Ana could cause a storms surge of up to six feet (2 meters) along the northern coast of Mozambique.

Tropical Cyclone Eloise Makes Landfall in Mozambique

Tropical Cyclone Eloise made landfall on the coast of Mozambique on Friday night. At 11:00 p.m. EST on Friday the center of Tropical Cyclone Eloise was located at latitude 20.4°S and longitude 34.6°E which put it about 45 miles (75 km) south-southwest of Beira, Mozambique. Eloise was moving toward the west-southwest at 14 m.p.h. (22 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 967 mb.

The center of Tropical Cyclone Eloise made landfall on the coast of Mozambique just to the south of Beira on Friday night. Eloise continued to intensify until the center made landfall. A small circular eye was evident on satellite images when Tropical Cyclone Eloise approached the coast. The eye was surrounded by a ring of strong thunderstorms and the strongest winds were occurring in that ring of storms. Winds to hurricane/typhoon force extended out 20 miles (30 km) from the center of E;poise. Winds to tropical storm force extended out 125 miles (200 km) from the center.

It is likely that the northern eyewall of Tropical Cyclone Eloise produced winds of near hurricane/typhoon force in Beira. Southerly winds blowing water toward the coast may have caused a storm surge of up to 6 to 9 feet (2 to 3 meters). Eloise was continuing to produce gusty winds and heavy rain in the region around Beira. The tropical cyclone will weaken gradually as it moves inland over central Mozambique.

Tropical Cyclone Eloise will move around the northwestern part of a high pressure system over the Southwest Indian Ocean and southern Africa. The high will steer Eloise toward the west-southwest during the next 36 hours. On its anticipated track Tropical Cyclone Eloise will drop heavy rain over parts of central Mozambique, southern Zimbabwe, northern South Africa and eastern Botswana. Heavy rain could cause flash floods in some locations.

Tropical Cyclone Eloise Intensifies to Equivalent of Hurricane/Typhoon

Tropical Cyclone Eloise intensified to the equivalent of a hurricane/typhoon on Friday. At 4:00 a.m. EST on Friday the center of Tropical Cyclone Eloise was located at latitude 19.0°S and longitude 37.5°E which put it about 190 miles (305 km) east-northeast of Beira, Mozambique. Eloise was moving toward the west-southwest 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 974 mb.

Tropical Cyclone Eloise intensified to the equivalent of a hurricane/typhoon near the coast of Mozambique on Friday morning. The inner end of a rainband wrapped around the center of Eloise and an eye was visible on satellite images. A ring of strong thunderstorms surrounded the eye want the strongest winds were occurring in that ring of storms. Winds to hurricane/typhoon force extended out 30 miles (50 km) from the center of Tropical Cyclone Eloise. Winds to tropical storm force extended out 125 miles (200 km) from the center of circulation.

Tropical Cyclone Eloise will move through an environment favorable for intensification during the next few hours. Eloise will move over water in the Mozambique Channel where the Sea Surface Temperature is near 29°C. It will move under the northern portion of an upper level ridge over the Southwest Indian Ocean and southern Africa. The ridge will produce easterly winds which will blow toward the top of the tropical cyclone. Those winds will cause some vertical wind shear but the shear will not be strong enough to prevent intensification. Tropical Cyclone Eloise is likely to get stronger today.

Tropical Cyclone Eloise will move around the northwestern part of a high pressure system over the Southwest Indian Ocean during the next two days. The high will steer Eloise toward the west-southwest. On its anticipated track Tropical Cyclone Eloise will make landfall on the coast of Mozambique near Beira in less than 12 hours. Eloise will be the equivalent of a hurricane/typhoon when it approaches the coast.

Tropical Cyclone Eloise will bring winds to hurricane/typhoon force to the area around Beira, Mozambique. Eloise will weaken after it moves inland, but it will drop heavy rain over parts of central Mozambique, southern Zimbabwe, southern Botswana, and northern South Africa. Heavy rain could cause flash floods in some locations.

Tropical Cyclone Chalane Makes Landfall in Mozambique

Tropical Cyclone Chalane made landfall in Mozambique on Tuesday night. At 9:00 p.m. EST on Tuesday the center of Tropical Cyclone Chalane was located at latitude 19.5°S and longitude 35.3°E which put it about 50 miles (80 km) northeast of Beira, Mozambique. Chalane was moving toward the west at 13 m.p.h. (20 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 981 mb.

Tropical Cyclone Chalane made landfall just to the north of Beira, Mozambique on Tuesday night. Chalane intensified until it made landfall. Tropical Cyclone Chalane was almost the equivalent of a hurricane/typhoon at the time of landfall. An elliptical eye was at the center of Chalane. The eye was surround by a ring of strong thunderstorms and the strongest winds were occurring in that ring of storms. Winds to tropical storm force extended out 80 miles (130 km) from the center of Chalane.

Tropical Storm Chalane will move north of a high pressure system over southern Africa and the Southwest Indian Ocean. The high will steer Chalane toward the west during the next 36 hours. On its anticipated track Tropical Cyclone Chalane will move across central Mozambique and Zimbabwe. Chalane will weaken steadily as it moves farther inland. It will drop heavy rain over parts of central Mozambique and Zimbabwe. Heavy rain could cause flash floods in some locations.

Tropical Cyclone Idai Drops Heavy Rain on Mozambique and Zimbabwe

Tropical Cyclone Idai dropped heavy rain on parts of Mozambique and Zimbabwe on Friday.  At 11:00 p.m. EDT on Friday the center of Tropical Cyclone Idai was located at latitude 19.0°S and longitude 32.5°E which put it about 50 miles (80 km) southwest of Mutare, Zimbabwe.  Idai was moving toward the west-northwest at 7 m.p.h. (11 km/h).  The maximum sustained wind speed was 45 m.p.h. (75 km/h) and there were wind gusts to 60 m.p.h. (95 km/h).  The minimum surface pressure was 985 mb.

Although the wind speeds around Tropical Cyclone Idai decreased steadily on Friday, the circulation remained very well organized.  An inner rainband wrapped most of the way around a well defined center of circulation.  Bands of showers and thunderstorms were revolving around the center of Idai.  The strongest bands were occurring in the southern half of the circulation.  Storms near the core of the circulation were still generating upper level divergence which was pumping mass away from the tropical cyclone.

Tropical Cyclone Idai dropped heavy rain from the coast of central Mozambique near Beira where Idai caused significant damage westward to the eastern Zimbabwe.  Persistent heavy rain was likely causing flooding along some of the rivers in central Mozambique and eastern Zimbabwe.  Tropical Cyclone Idai is forecast to continue to move toward the west-northwest and heavy rain is likely to spread over more of Zimbabwe.

Tropical Cyclone Idai Makes Landfall in Mozambique

Strong Tropical Cyclone Idai made landfall in Mozambique very close to Beira on Thursday.  At 11:00 p.m. EDT on Thursday the center of Tropical Cyclone Idai was located at latitude 19.4°S and longitude 34.5°E which put it about 30 miles (50 km) northwest of Beira, Mozambique.  Idai was moving toward the west at 8 m.p.h. (13 km/h).  The maximum sustained wind speed was 105 m.p.h. (170 km/h) and there were wind gusts to 125 m.p.h. (205 km/h).  The minimum surface pressure was 958 mb.

The core of Tropical Cyclone Idai moved directly over Beira, Mozambique.  The eye moved over Beira.  The maximum sustained wind speed was 110 m.p.h. (175 km/h) and there were wind gusts to 130 m.p.h. (210 km/h) at the time of landfall.  Winds to hurricane/typhoon force extended out about 25 miles (40 km) from the center of circulation.  Winds to tropical storm force extended out about 150 miles from the center of Tropical Cyclone Idai.

The Hurricane Intensity Index (HII) for Tropical Cyclone Idai was 19.2 at the time of landfall.  The Hurricane Size Index (HSI) was 13.8 and the Hurricane Wind Intensity Size Index (HWISI) was 33.0.  Tropical Cyclone Idai was capable of causing very serious wind damage.  Both sides of the eyewall which contained the strongest winds moved over Beira.  The relatively slow rate at which Idai was moving would have resulted in a prolonged period of strong winds, which would have increased the potential for damage.

Clockwise rotation around Tropical Cyclone Idai would have produced strong southerly winds when Idai approached Beira.  Those winds would have pushed water into the mouth of the Rio Pungoe which is on the western side of Beria.  There could have been an enhanced storm surge of 12 to 18 feet (4 to 6 meters) in that area.  Beira is one of the largest cities in Mozambique and it has a population of over half a million people.  Idai could have cause very serious damage around Beira.

Tropical Cyclone Idai will move toward the west-northwest during the next day or two.  On its anticipated track Idai will move farther inland over Mozambique and it will eventually move over Zimbabwe.  Tropical Cyclone Idai will weaken steadily as it moves inland, but it will drop heavy rain over central Mozambique and over parts of Zimbabwe.  The heavy rain could cause flooding along portions of Rio Pungoe and Rio Buzi as well as other parts of central Mozambique and Zimbabwe.

Tropical Cyclone Dineo Makes Landfall in Mozambique

Tropical Cyclone Dineo made landfall on the coast of Mozambique near Massinga on Wednesday.  Dineo intensified prior to landfall.  The maximum sustained wind speed at the time of landfall was 85 m.p.h. (135 km/h) and there were wind gusts to 105 m.p.h. (170 km/h).  Tropical Cyclone Dineo was capable of causing minor wind damage.  It may have produced a storm surge near and to the south of where the center made landfall.  Tropical Cyclone Dineo is producing locally heavy rain as it moves inland over Mozambique.

At 10:00 p.m. EST on Wednesday the center of Tropical Cyclone Dineo was located at latitude 23.3°N and longitude 33.6°E which put it about 125 miles (205 km) west-northwest of Inhambane, Mozambique.  Dineo was moving toward the west at 11 m.p.h. (17 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 981.

Even though it has moved inland the structure of Tropical Cyclone Dineo is still very well organized.  The remnants of the eye and the eyewall are still visible on satellite imagery.  There are several rainbands rotating around the core of Tropical Cyclone Dineo.  The strongest winds are occurring in thunderstorms in the bands that are still offshore over the Indian Ocean.  The thunderstorms near the center of Dineo are still generating upper level divergence which is pumping mass away from the core of the tropical cyclone.

Tropical Cyclone Dineo will continue to weaken slowly as it moves farther inland.  The atmospheric environment is favorable for a tropical cyclone.  The upper level winds are weak and there is little vertical wind shear.  However, now that the core of Dineo is inland, it is away from the warm water of the Indian Ocean which fueled the tropical cyclone’s intensification.  So, Tropical Cyclone Dineo will spin down, but at a slower rate than occurs with some landfalling tropical cyclones.

A subtropical ridge is steering Tropical Cyclone Dineo toward the west and that general motion is expected to continue.  On its anticipated track the center of Tropical Cyclone Dineo could pass near Dindiza, Chigubo and Mapai in Mozambique.  Dineo could produce locally heavy rain when it moves over those areas.  Tropical Cyclone Dineo or its remnants could also bring locally heavy rain to parts of northern South Africa, southern Zimbabwe and eastern Botswana.
