Tropical Low Prompts Warning for Queensland

A Tropical Low over the Coral Sea prompted the Australian Bureau of Meteorology to issue a Warning for the coast of Queensland on Thursday night.  At 7:00 a.m. EST on Friday the center of the Tropical Low was located at latitude 14.9°S and longitude 148.1°E which put the center about 210 miles (335 km) northeast of the Cairns, Australia.  The Tropical Low was moving toward the south-southwest at 4 m.p.h. (6 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 995 mb.

The Australian Bureau of Meteorology issued a Warning for the portion of the coast of Queensland from Port Douglas to Airlie Beach.  The Warning includes Cairns, Innisfail, Townsville and Bowen.

A low pressure system over the Coral Sea was strengthening on Friday morning.  The Australian Bureau of Meteorology was classifying the system as a Tropical Low.  The U.S. Joint Typhoon Warning Center was designating the system as Invest 92P.

A Tropical Low over the Coral Sea was strengthening on Friday morning.  Thunderstorms were occurring in bands in the northwestern part of the Tropical Low.  Another cluster of thunderstorms was located southeast of the center of circulation.  Storms near the center began to generated upper level divergence that pumped mass away from the Tropical Low.  The removal of mass caused the surface pressure to decrease.

The strongest winds were occurring in the thunderstorms northwest and southeast of the center of the Tropical Low.  Winds to tropical storm force extended out 140 miles (225 km) from the center of circulation.

The Tropical Low will move through an environment favorable for intensification during the next 24 hours.  The Tropical Low will move over water where the Sea Surface Temperatures are near 28°C.  It will move through a region where the upper level winds are weak and there will be little vertical wind shear.  The Tropical Low is very likely to intensify to a named tropical cyclone during the next 24 hours.

The Tropical Low will move around the western side of a high pressure system that is east of Australia.  The high pressure system will steer the Tropical Low toward the south-southwest during the next 24 hours.  On its anticipated track, the Tropical Low will approach the coast of Queensland near Townsville in 24 hours.

The Tropical Low is likely to be the equivalent of a tropical storm when it approaches the coast.  It will bring strong winds and locally heavy rain to the portion of the coast between Port Douglas and Airlie Beach.  Heavy rain could cause flash floods in some locations.

Tropical Cyclone Forming over Solomon Islands

A tropical cyclone is forming over the Solomon Islands. The system is currently designated as Invest 92P by the U.S. Joint Typhoon Warning Center. At 1:00 a.m. EST on Monday the center of Invest 92P was located at latitude 8.7°S and longitude 158.3°E which put it about 130 miles (210 km) west-northwest of Honiara, Guadacanal. Invest 92P was moving toward the southwest at 8 m.p.h. (13 km/h). The maximum sustained wind speed was 30 m.p.h. (50 km/h) and there were wind gusts to 40 m.p.h. (65 km/h). The minimum surface pressure was 1002 mb.

A low pressure system over the Solomon Islands was gradually becoming better organized on Monday morning. The U.S. Joint Typhoon Warning Center was designating the system as Invest 92P. The Australian Bureau of Meteorology classified the system as a tropical low. Bands of showers and thunderstorms were revolving around the center of the low pressure system. Storms near the center generated upper level divergence that pumped mass away from the low pressure system. The removal of mass was causing the surface pressure to decrease.

The low pressure system will move through an environment favorable for the development of a tropical cyclone during the next 36 hours. The low pressure system will move over water where the Sea Surface Temperatures are near 29°C. It will move under the western part of an upper level ridge over the South Pacific Ocean. The upper level ridge will produce northerly winds that will blow toward the top of the low pressure system. Those winds will cause some vertical wind shear, but the wind shear will not be enough to prevent intensification. Invest 92P is very likely to develop into a tropical cyclone during the next 36 hours.

The low pressure system will move around the northwestern part of a high pressure system over the South Pacific Ocean. The high pressure system will steer Invest 92P toward the southwest during the next 36 hours. On its anticipated track, the low pressure system will move away from the Solomon Islands and over the Coral Sea. Invest 92P will continue to produce gusty winds and locally heavy rain in the Solomon Islands until it moves away. Heavy rain could cause flash floods in some locations.
