Category 1 has been issued due to expected multicell (and pulse-type) storms in the evening hours mainly in the southwestern part of Hungary (and subsequently, at dawn over the Transdanubian area). The storms can produce strong gusts (up to 90 km/h and slightly above), large hail (around 2 cm), and flash floods in some places.

Supercell convection can be expected in the next one and a half days in the eastern part of Hungary (Tiszántúl). The supercells may form a convective system mainly during the night and in the morning. Subsequently, there is a chance that isolated supercells will form tomorrow in the afternoon but the high convective inhibition (resembling of a loaded gun case) may prevent their outburst. The main severe threats are: flash floods,  large hail (above 2 cm up to 3-4 cm), and wind gusts (between 90 and 120 km/h, in bow echos in the afternoon above 120 km/h).
