Severe storms firing up over the Gold Coast

Damaging winds and heavy rainfall for the Gold Coast and south-east Queensland are expected over the next several hours as severe thunderstorms develop.

The City of Gold Coast's Disaster Management Unit provided the following information around midday (via Cr Glenn Tozer for Division 9)

A line of developing showers and storms was located on radar from Millmerran-Warwick-Kyogle at about 12pm today. This line may intensify as it reaches the coastline due to increased moisture and instability.

Storms in Northeast NSW have already been stronger than expected, and as such consider an increased risk of thunderstorm and severe thunderstorm activity in Southeast Queensland this afternoon. Pay particular attention to any large storm clusters that suddenly take a more northward move from the favoured E/NE trajectory as this would be a sign of severity.

Large hail and flash flooding are both reasonable risks today (Evans Head recorded 41mm in 10 minutes this morning). Damaging winds are also possible, though storms containing damaging winds are less likely to last as long (because the surface winds today are relatively weak and storms with strong winds in these environments tend to weaken quickly unless surface winds into the storm are also strong)
