Wet in
NT as ex-TC Sam moves slowly east Heavy rain on Qld tropical coast Hot around Sydney, cold in the tropics |
||
Heavy rain moved across central
southern NT today as former tropical cyclone Sam drifted slowly into
the Tanami Desert from Western Australia. The rain depression has maintained
a strong identity, with central pressure today around 988hPa, bringing heavy
downpours to the Tanami, Victoria River and Barkly districts. Epenarra,
140km SE of Tennant Creek, has recorded 102.8mm in the 2 days to 9 this
morning, while Wycliffe Well, 130km S of Tennant Creek recorded 184.8mm
in 3 days ended 9am Wednesday. Other heavy falls are given below and in
Wednesday's rain list. Many roads in southern NT are now impassable because
of the rain. The Mereenie loop road west of Alice Springs, the Plenty Highway
northeast to Queensland and the Tanami Highway northwest to WA all closed.
An active monsoon trough continues to extend from ex-TC Sam across the southeastern Gulf of Carpentaria and NE across Cape York Peninsula. Heavy storms that developed in the eastern Gulf last night drifted across the Peninsula during the early morning giving Lockhart River on the east coast 95mm in 12 hours to 3am and Cape Keerweer on the west coast 125mm for the 24 hours to 9am. An intense shower gave South Johnstone, 8km SSW of Innisfail, 48.8mm in just 20 minutes to 2.19am with 31.6mm falling in the last 10 minutes.
Hot weather continued in western NSW today, with top temperatures again around 42 or 43 degrees. Northwesterly winds brought the heat to the coast around Sydney, giving the city temperatures 12 to 13° above normal during the day. Meanwhile, heavy cloud cover associated with ex-TC Sam and the monsoon trough kept daytime temperatures 10 to 15 below normal in a band across the north of the continent. Balgo Hills, near the WA/NT border and between the Great Sandy and Tanami Deserts, recorded a top temp of only 23.9, 15.6 below the average. |
