Tropical Cyclone Nisagra Makes Landfall South of Mumbai

Tropical Cyclone Nisarga made landfall south of Mumbai, India on Wednesday.  At 5:00 a.m. EDT on Wednesday the center of Tropical Cyclone Nisarga was located at latitude 18.3°N and longitude 73.3°E which put it about 80 miles (130 km) south of Mumbai, India.  Nisarga was moving toward the northeast at 12 m.p.h. (19 km/h).  The maximum sustained wind speed was 85 m.p.h. (135 km/h) and there were wind gusts to 105 m.p.h. (165 km/h).  The minimum surface pressure was 973 mb.

Tropical Cyclone Nisarga rapidly intensified into the equivalent of a hurricane/typhoon on Tuesday night before it made landfall on the west coast of India.  An eye with a diameter of 40 miles (65 km) formed at the center of Nisarga.  A ring of strong thunderstorms surrounded the eye and 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 Nisarga at the time of landfall.  Winds to tropical storm force extended out 100 miles (160 km) from the center.

Tropical Cyclone Nisarga brought winds to hurricane/typhoon force to a portion of the west coast of India south of Mumbai.  Those winds would have pushed water toward the coast.  The would have generated a storms surge of 3 to 6 feet (1 to 2 meters) near where the center of Nisarga made landfall.  Tropical Cyclone Nisarga will drop heavy rain over parts of Maharashtra.  Heavy rain could cause flash floods in some locations.

Strengthening Tropical Cyclone Nisarga Nears Mumbai

Strengthening Tropical Cyclone Nisarga neared  Mumbai, India on Tuesday night.  At 11:00 p.m. EDT on Tuesday the center of Tropical Cyclone Nisarga was located at latitude 17.6°N and longitude 72.4°E which put it about 140 miles (225 km) south-southwest of Mumbai, India.  Nisarga was moving toward the northeast at 7 m.p.h. (11 km/h).  The maximum sustained wind speed was 65 m.p.h. (105 km/h) and there were wind gusts to 80 m.p.h. (130 km/h).  The minimum surface pressure was 985 mb.

Tropical Cyclone Nisarga strengthened quickly on Tuesday night as it moved closer to the west coast of India.  An eye with a diameter of 40 miles (65 km) formed at the center of circulation.  A ring of thunderstorms surrounded the eye and the strongest winds were occurring in that ring of storms.  Bands of showers and thunderstorms were revolving around the core of Nisarga.  Storms near the core were generating upper level divergence which was pumping mass away to the east of the tropical cyclone.  Winds to tropical storm force extended out 100 miles (160 km) from the center of circulation.

Tropical Cyclone Nisarga will move around the western end of a high pressure system over India.  The high will steer Nisarga toward the northeast during the next 24 hours.  On its anticipated track the center of Tropical Cyclone Nisarga will make landfall on the west coast of India south of Mumbai in a few hours.

Tropical Cyclone Nisarga will continue to intensify until it makes landfall.  Nisarga will move over water where the Sea Surface Temperature is near 31°C.  It will move under the western part of an upper level ridge centered over India.  The ridge will produce southerly winds which will blow toward the top of Nisarga.  Those winds will cause some vertical wind shear, but the shear will not be great enough to prevent intensification.  Tropical Cyclone Nisarga is likely to strengthen into the equivalent of a hurricane/typhoon before it makes landfall.

Tropical Cyclone Nisarga will bring strong winds to the west coast of India.  Those winds will push water toward the coast and they could cause a storm surge of 3 to 6 feet (1 to 2 meters) near Mumbai and near where the center makes landfall.  Nisarga will also drop heavy rain over parts of Maharashtra.  Locally heavy rain could cause flash floods in some locations.

Tropical Cyclone Nisarga Develops West of India

Tropical Cyclone Nisarga developed west of India on Tuesday.  At 5:00 a.m. EDT on Tuesday the center of Tropical Cyclone Nisarga was located at latitude 16.0° and longitude 71.2°E which put it about 225 miles (365 km) south-southwest of Mumbai, India.  Nisarga was moving toward the north at 8 m.p.h. (13 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 1000 mb.

The circulation around a low pressure system over the Arabian Sea west of India strengthened on Tuesday and the India Meteorological Department designated the system as Tropical Cyclone Nisarga.  More thunderstorms developed near the center of Nisarga.  Numerous bands of showers and thunderstorms were revolving around the center of circulation.  The strongest rainbands were in the western half of the tropical cyclone.  Storms near the center of circulation generated upper level divergence which pumped mass away from the tropical cyclone.

Tropical Cyclone Nisarga will move through an environment favorable for intensification during the next 24 hours.  Nisarga will move over water where the Sea Surface Temperature is near 31°C.  It will move under the western side of an upper level ridge centered over India.  The ridge will produce southerly winds which will blow toward the top of the circulation.  Those winds will produce some vertical wind shear, but the shear will not be strong enough to prevent the intensification of Tropical Cyclone Nisagra.  Nisagra could strengthen into the equivalent of a hurricane/typhoon.

Tropical Cyclone Nisarga will move around the western end of a high pressure system over India.  The high will steer Nisarga toward the north during the next 12 hours.  Nisarga will move more toward the north-northeast when it moves around the northwestern part of the high pressure system.  On its anticipated track Tropical Cyclone Nisarga could approach Mumbai in about 24 hours.  Nisarga could be the equivalent of a hurricane/typhoon when it approaches Mumbai.

Tropical Cyclone Nisarga will bring gusty winds and locally heavy rain to Mumbai on Wednesday.  Nisarga could also cause a storm surge of  3 to 6 feet (1 to 2 meters) in the area around Mumbai where the wind blows the water toward the coast.  Tropical Cyclone Nisarga will drop locally heavy rain over parts of Maharashtra and southern Gujarat.  Heavy rain could cause flash floods in some locations,
