Tropical Cyclone Alvaro brought wind and rain to southern Madagascar on Monday. At 10:00 p.m. EST on Monday the center of Tropical Cyclone Alvaro was located at latitude 21.5°S and longitude 45.3°E which put it about 40 miles (65 km) north of Fianarantsoa, Madagascar. Alvaro was moving toward the east at 12 m.p.h. (19 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 997 mb.

The center of Tropical Cyclone Alvaro made landfall on the coast of southwest Madagascar north of Morombe on Monday. Alvaro was near hurricane/typhoon intensity at the time of landfall. A circular eye was at the center of Alvaro’s circulation at the time of landfall. Winds to tropical storm force extended out 85 miles (135 km) from the center of circulation. Tropical Cyclone Alvaro moved eastward across southern Madagascar and the center was north of Fianarantsoa on Sunday night. Heavy rain was falling over parts of southern Madagascar.

Tropical Cyclone Alvaro weakened after it moved over southern Madagascar on Monday, but Alvaro’s circulation continued to exhibit organization. Bands of showers and thunderstorms were revolving around the center of circulation. Storms near the center of Alvaro generated upper level divergence that pumped mass away to the east of the tropical cyclone. Winds to tropical storm force extended out 60 miles (95 km) from the center of Tropical Cyclone Alvaro.

Tropical Cyclone Alvaro will continue to weaken while the center of circulation moves eastward over southern Madagascar. The center of Alvaro’s circulation could move over the southwest Indian Ocean east of Madagascar in 24 hours. Tropical Cyclone Alvaro will move into an environment somewhat favorable for intensification when it moves back over water. Alvaro will move over water where the Sea Surface Temperatures are near 28°C. It will move under the southern part of an upper level ridge over the southwest Indian Ocean. The upper level ridge will produce westerly winds that will blow toward the top of Alvaro’s circulation. Those winds will cause moderate vertical wind shear. The wind shear will inhibit intensification, but the shear may not be enough to prevent some intensification. Tropical Cyclone Alvaro could intensify when the center moves back over water east of Madagascar.

The upper level ridge over the Mozambique Channel will steer Tropical Cyclone Alvaro toward the east-southeast during the next 24 hours. On its anticipated track, Tropical Cyclone Alvaro will continue to move eastward across southern Madagascar. Heavy rain could cause flash floods in some parts of southern Madagascar. Alvaro will move off the coast of southeast Madagascar between Mananjary and Manakara in about 24 hours. Tropical Cyclone Alvaro could pass south of La Reunion and Mauritius later this week.
