March 22, 2019 – Tropical Cyclone Trevor Fills Australia’s Gulf of Carpentaria in NASA Image

Visible imagery from NASA’s Aqua satellite showed Tropical Cyclone Trevor filling up Australia’s Gulf of Carpentaria.

The Gulf of Carpentaria is a large, shallow sea. It is surrounded on three sides by northern Australia and bounded by the Arafura Sea to the north.

Trevor had crossed the Cape York Peninsula on March 21 and moved into the Gulf. On On March 22 the Moderate Resolution Imaging Spectroradiometer or MODIS instrument aboard NASA’s Aqua satellite provided a visible image of Trevor. Satellite imagery revealed that Trevor’s clouds had filled up the Gulf. It showed that bands of thunderstorms circled more tightly around the center of circulation than the previous day.

The Australian Bureau of Meteorology or ABM updated warnings and watches on March 22, 2019. The Warning Zone includes Alyangula in the Northern Territory to Burketown in Queensland, and inland parts of the eastern Carpentaria District and the northwest Gulf Country, including Groote Eylandt, Mornington Island, Borroloola, Robinson River, Wollogorang, McArthur River, Cape Crawford, Creswell Downs, Brunette Downs and Doomadgee. The Watch Zone includes inland parts of the northwest Gulf Country in Queensland and the western Carpentaria and central Barkly Districts in the Northern Territory.

At 8 a.m. EDT (9:30 p.m. Australian Central Standard Time or ACST) on March 22, 2019, maximum sustained winds near Trevor’s center were near 90 miles (150 kilometers) per hour. Trevor was centered near 15.0 degrees south latitude and 138.9 degrees east longitude. That’s about 110 miles (185 kilometers) north or Mornington Island.

ABM noted “Dangerous conditions are expected tonight along the southern Gulf of Carpentaria coast as Severe Tropical Cyclone Trevor approaches. The cyclone is expected to cross the coast during Saturday morning, March 23, between Port McArthur and the Northern Territory/Queensland border.”

Destructive winds, very heavy rainfall and storm surge are expected with this storm. ABM said “Coastal residents between Port Roper and the NT/Queensland Border are specifically warned of a very dangerous storm tide as the cyclone center approaches the coast. Tides will rise significantly above the normal high tide, with damaging waves and very dangerous flooding during Friday night and Saturday. As the cyclone approaches the coast, a storm tide is also expected between the Northern Territory/Queensland border and Burketown. Large waves may produce minor flooding along the foreshore.”

Mar. 21, 2019 – NASA Sees Tropical Cyclone Trevor Move Into Gulf of Carpentaria

Tropical Cyclone Trevor has crossed Queensland, Australia’s Cape York Peninsula and re-emerged into the Gulf of Carpentaria. Visible imagery from NASA’s Terra satellite confirmed the movement back over water.

Tropical Cyclone Trevor is expected to intensify in the Gulf of Carpentaria. A severe impact on the southwestern Gulf of Carpentaria coast is likely over the weekend, according to the Australian Bureau of Meteorology or ABM.

On March 21 the Moderate Resolution Imaging Spectroradiometer or MODIS instrument aboard NASA’s Terra satellite provided a visible image of Trevor. Trevor hadn’t strengthened enough over water yet to develop an eye in visible imagery, but the center was surrounded by powerful thunderstorms. Microwave satellite imagery suggests that an eye has re-developed.

ABM updated warnings and watches on March 21, 2019. The Warning zone stretches from Cape Shield in the Northern Territory to Burketown in Queensland, including Borroloola, Groote Eylandt and Mornington Island, and Kowanyama to Aurukun. Watch Zone goes from Burketown to Karumba.

At 11 a.m. EDT on March 21, (12:30 a.m. AWST Australian Eastern Standard Time on March 22), maximum sustained winds near Trevor’s center were near 68 miles (110 kilometers) per hour. Trevor was a strong tropical storm. Trevor was located near 13.9 degrees South latitude and 140.6 degrees East longitude, about be 84 miles (135 kilometers) west southwest of Aurukun and 283 miles (455 kilometers) east of Alyangula. Tropical Cyclone Trevor is located over water in the eastern Gulf of Carpentaria.

ABM forecasts that “Tropical Cyclone Trevor will intensify further as it adopts a more general southwest movement across the Gulf of Carpentaria tonight and during Friday. It is likely to cross the Northern Territory coast during Saturday as a category 4 severe tropical cyclone.” Trevor is expected to make landfall near Borroloola.

Mar. 20, 2019 – NASA’s Terra Satellite Tracks Tropical Cyclone Trevor Over Cape York Peninsula

Visible imagery from NASA’s Terra satellite showed Tropical Cyclone Trevor was moving west over Queensland, Australia’s Cape York Peninsula and toward the Gulf of Carpentaria.

On March 20 the Moderate Resolution Imaging Spectroradiometer or MODIS instrument aboard NASA’s Terra satellite provided a visible image of Trevor.

The Australian Bureau of Meteorology or ABM has posted warnings and watches. The Warning zone ranges from Pormpuraaw to Cape York. The Watch zone includes Nhulunbuy to Northern Territory/Queensland border and Kowanyama to Pormpuraaw.

At 9:21 a.m. EDT (11:21 p.m. AEST Australia local time) on March 20, 2019, maximum sustained winds near Trevor’s center were near 40 miles (65 kilometers) per hour. Trevor was centered near 12.9 degrees south latitude and 141.8 degrees east longitude. That’s about 19 miles (30 kilometers) south-southwest of Weipa. The cyclone is expected to move offshore over the eastern Gulf of Carpentaria tonight, where it is expected to rapidly intensify.

ABM forecasts that Trevor will move to the west-southwest through the Gulf of Carpentaria over the next couple of days and make landfall on March 23, north of Port McArthur, Northern Territory. ABM noted “It is likely to cross the Northern Territory coast during Saturday as a category 4 severe tropical cyclone.”

Mar. 19, 2019 – NASA Tracks Tropical Cyclone Trevor Approaching Australia’s Cape York Peninsula

Tropical Cyclone Trevor appeared to have a cloud-filled eye in visible imagery from NASA-NOAA’s Suomi NPP satellite.

On March 19, 2019 the Visible Infrared Imaging Radiometer Suite (VIIRS) instrument aboard NASA-NOAA’s Suomi NPP satellite captured visible image of Tropical Cyclone Trevor as it continued moving west through the Coral Sea, Southern Pacific Ocean, and toward a landfall in Queensland, Australia’s Cape York Peninsula. VIIRS imagery showed powerful thunderstorms wrapping into the low-level center. At the time of the image, Trevor’s western quadrant was already over the Peninsula, and the eye appeared covered by high clouds.

After the Suomi NPP image, Trevor crossed the coast in the evening (local time) and remains slow moving just south of Lockhart River.

On March 18 (EDT), the Australian Bureau of Meteorology or ABM posted a warning from Orford Ness to Cape Melville, including Lockhart River and Coen, and Pormpuraaw to Cape York, including Weipa and Aurukun.

At 8:51 a.m. EDT (10:51 p.m. AEST local time, Australia), the ABM noted that maximum sustained winds near the center were 130 kilometers per hour (80 mph). Trevor’s center was located near 12.9 degrees south and 143.3 degrees east, about 15 kilometers (8 miles) south of Lockhart River and 160 kilometers (9 miles) east southeast of Weipa. Trevor was moving to the west.

ABM said “The cyclone will weaken as it crosses the northern Peninsula tonight and Wednesday, but is expected to remain a category 1 cyclone until it enters the Gulf of Carpentaria later on Wednesday. It is expected to re-intensify rapidly once it enters the Gulf of Carpentaria and track towards the Northern Territory.”
