Ongoing severe MCS over Balearic islands – Oct 29, 18:00 UTC

Explosive severe convection in the morning over Balearic islands quickly intensified and soon organized into a large severe Mesoscale Convective System within the SLGT+ risk area of DAY 1 Outlook for 29/10/2013.

A lot of severe events were reported. Over 110 km/h severe wind gusts, local heavy downpours (60+ mm in 30 minutes) and even a tornado, accompanied the slowly propagating convective system.

The tornado was reported at 13:30 UTC, lasting up to 5 minutes. Touchdown was over water, so there are no damage reports related to the tornado event.

Currently, the severe convective system is still active and slowly propagating towards SSE. Special satellite imagery features very high thunderstorms tops (exceeding 13 km) and an “anvil plume“, all indicating the severe intensity and organisation of the large system.

Latest radar scans and lightning observations indicate the convective system is still severe, but the strongest storms are now moving over open waters of the Mediterranean Sea.
