A MDT+ risk has been issued for E-NE Adriatic coastal areas with threat for extremely severe non-convective wind gusts, locally in excess of 150 km/h for 12+ hours.

Area will likely be upgraded into HIGH risk on DAY 1.
A MDT risk has been issued for areas along the Adriatic and Ionian sea with threat for torrential excessive rain, severe winds, tornadoes and some hail threat. MDT risk was also extended into eastern parts of central Italy where excessive rain threat appears possible with strong upslope flow from the Adriatic sea.

A SLGT+ risk has been issued for S Italy into S Mediterranean with threat for tornadoes, torrential excessive rain, large hail and severe winds. Some uncertainities exist for coverage of severe storms, so area is monitored for possible upgrade into MDT risk on DAY 1.
