DISCUSSION

ENH / SLGT risks have been issued for parts of N Atlantic into NW Iceland with threat for severe to extremely severe winds in excess of 120 km/h.

SLGT risk has been issued for parts of coastal N Norway (Lofoten) with threat for severe winds, locally reaching 90-110 km/h.

SLGT risk has been issued for E Tunisia into S Mediterranean for severe storms, capable of producing marginal hail, severe winds and torrential rainfall. Favorable shear parallel to the frontal boundary should lead into excessive rainfall (80-100 mm per 24 hours) across Lampedusa island towards ENE Tunisia.

TSTM risk areas have been placed where convective storms are likely to occur.
