Hobart was battered by rain and hail as thunderstorms moved across parts of Tasmania. A low pressure system and associated trough moved over the state's southeast this morning, triggering severe thunderstorms. These storms have been moving along the East Coast this afternoon as the trough moves north. Heavy rain amounted to 4mm in Cape Sorell and 2mm at Hobart Airport in a period of just 10 minutes this morning. The highest accumulated falls between 9am and 2:30pm were in Tannack, which recorded 17mm and Grove, with 11mm. For Tannack, this was the heaviest rain since August. Thunderstorms over the state's capital city also resulted in reports of tornado sightings, hail and localised flash flooding. Showers and isolated storms are still a risk in Hobart this afternoon, although conditions will become more stable this evening as a ridge of high pressure moves into the region. The weekend looks much calmer, with mostly sunny skies and temperatures climbing into the low 20s on Sunday.
