‘Triple digit threat’: Severe weather for millions
Written by admin on November 28, 2024
Australia’s east coast is set to see a pounding on Thursday as a storm front, which has already smashed Melbourne, heads toward Sydney.
Forecasters have warned that severe thunderstorms could led to “triple digits” in rainfall gauges – a recipe for dangerous conditions and possible flash flooding.
“We continue to see storms possible across all parts of eastern Australia,” said Bureau of Meteorology (BOM) meteorologist Miriam Bradbury.
“But notably, severe storms remain a risk for parts of New South Wales and northern Tasmania in particular and we have an area of likely severe thunderstorms that includes Sydney and The Central Coast, southern parts of the Hunter and the Illawarra, as well as the central Tablelands.”
Tragically, a 45-year-old man died in Yarrawonga, in Victoria’s north on Wednesday as storms ravaged the state.
A branch fell on a car which the man was inside.
The SES stated it received 364 calls for help in the 24 hours to 6pm on Wednesday with almost 100 buildings damaged and 15 rescue requests, reports the Herald Sun.
There were more than 60 reports of flash flooding, mostly around the city’s south east.
Wilsons Promontory received 25mm of rain in a mere 10 minutes on Wednesday afternoon.
Sydney hottest place on earth
On the same day, Sydney Airport was reportedly the hottest place on earth.
Meteorology website Weatherzone stated that Sydney Airport’s maximum of 38.2°C at 12.15pm saw it top the world heat chart.
That’s chiefly because the northern hemisphere is nearing the coolest part of the year, of course.
But other southern hemisphere areas, such as South Africa and southern Latin America, have not been unable to match Australia’s run of bakingly hot days.
Sydney to bear brunt of storms
There were concerns on Wednesday that the soaring temperatures in NSW could have led to blackouts due to increased electricity demand coupled with outages from power stations.
That outcome was avoided, mostly. However parts of Sydney CBD have no electricity on Thursday morning due to a flooded substation.
The reason behind the weather drama is a low pressure trough which is now marching into New South Wales bringing with it lots of moisture and unsettled storm conditions.
Sydney could see up to 80mm or rain over the next three days, or even more depending on how and when storms hit.
Thursday could reach 31C, so a reduction from Wednesday, but storms are likely and could be severe as the day progresses.
The storms could bring a concentrated deluge of up to 15mm during a short period as well as large hail and damaging winds, the BOM has warned.
‘Triple digits in the gauge’
There is also the chance of a storm on Friday with this time up to 35mm of rain. But the temperature should drop to the mid-twenties. On Saturday, the storm threat should diminish but 7-30mm of rain could still fall on Sydney.
“If severe storms move overhead we could easily see triple digits in the rainfall gauges and if that kind of rain falls in a short space of time that can lead to dangerous conditions,” said Ms Bradbury of storm affected areas of NSW.
Wollongong, Newcastle, Gosford, Goulburn, Katoomba, Orange and nearby areas are all on storm watch.
Canberra has a chance of thunderstorms on Thursday with a high of 31C but the more treacherous conditions could be on Friday when up to 20mm of rain may fall associated with storms. A further 15-50mm is forecast for Saturday.
Melbourne will see the unsettled conditions recede and blue skies take their place on Thursday and Friday with highs in the mid-twenties and very little rain.
But Saturday could be a washout with heavy falls again linked to storms, with 6-30mm falling.
It’ll be soggy in Hobart on Thursday with showers and up to 10mm in the gauge, then clearing for Friday before a wet weekend with potentially 45mm across both days.
Temperatures should rise from 16C on Thursday to a high of 22C on Sunday.
A cloudy Thursday in Adelaide with a high of 23C and little rain. A possible shower on Friday leading to a fine mid-twenties weekend.
It will be mostly dry in Brisbane on Thursday with a 30C maximum. Friday could see a few showers. The storms shouldn’t trouble southern Queensland but it could still be wet in Brisbane on the weekend with a possible 15mm on Saturday and 20mm on Sunday.
