Severe thunderstorms with large hail and damaging winds approaching Adelaide area

There has been a severe thunderstorm warning for the Adelaide region, predicting large hailstones and damaging winds.

Meteorologist Tina Donaldson has described the oncoming weather, and it sounds like we are going to have some crazy storms affecting the state during the week ahead.

There has been a severe thunderstorm warning for the Adelaide region, with large hailstones and damaging winds likely to hit the state.

Severe storms have been detected on the weather radar near Ardrossan and Curramulka. These thunderstorms are now moving towards the east, and are forecast to affect Adelaide City, Elizabeth, Glenelg, Noarlunga, Salisbury, Gawler and Nuriootpa with large hailstones and damaging winds occurring.

The State Emergency Service advises that people should:

  • Secure or put away loose items around your property.
  • Move cars under cover or away from trees.
  • Keep clear of fallen power lines.
  • Stay indoors, away from windows, while storms are nearby.

A more general severe thunderstorm warning is also current for the Adelaide Metropolitan, Mount Lofty Ranges, Lower Eyre Peninsula, Yorke Peninsula, Flinders, Kangaroo Island and parts of the West Coast, Eastern Eyre Peninsula, Mid North, Murraylands, Upper South East and North East Pastoral districts.

Warnings have also been issued for fire weather and costal waters, with other weather warnings likely during the next few days.

Severe thunderstorms that may produce hail will continue around parts of the country this week with giant hail.

Hail researchers have explained how tiny stones can grow to the size of a ten-cent piece, a cricket ball or even the record-breaking size of a mango.  

Hail can occur at any time of the year, but for large hailstones to form, conditions must be just right. 
 
According to the Bureau of Meteorology’s Dr Joshua Soderholm, in Australia, severe hailstorms are most common during spring and early summer. 

“This is a time of the year when surface temperatures are warm enough to promote the development of intense thunderstorms, but you also need the accompanying ingredients of strong winds and cool air in the upper atmosphere to support hail growth,” Dr Soderholm said.
