28-29 July It rained heavily in Lithuania. Very heavy rain fell at many stations of the Lithuanian Hydrometeorological Service (LHMS). Dangerous (15-49.9 mm, in ≤12 hours), severe (50-80 mm, in ≤12 hours) and catastrophic (>80 mm, in ≤12 hours) rains were recorded at all LHMS stations, except for Marijampolė AMS. The highest precipitation was recorded in Žemaitija and western part of Lithuania. Catastrophic rain was recorded at 5 meteorological stations: Telšiai (110.1 mm), Laukuva (97.3 mm), Šiauliai (93.1 mm), Joniškės (81.8 mm), Mažeikiai (80.7 mm). In 16 stations, cases of heavy rainfall were recorded.

The highest rainfall in Telšiai in a ≤12-hour period to date was 90.7 mm (1984) and 81 mm (1970) in Laukuva. Meanwhile, no catastrophic rainfall has ever been recorded in Šiauliai, Mažeikiai.

Cases of more than 100 mm of rainfall in less than 12 hours are extremely rare. Only a few such cases have been recorded in Lithuania since 1961: in 1961 in Žindaičiai (109.5 mm), in 1963 in Skuodas (113 mm), in 1980 in Sartai (200 mm), in 1985 in Aunuvėnai (110.6 mm), in Kyburi (111.7 mm) and in Pakruojis (115 mm), and in 2013 in Eidukai (104.7 mm) and in Kartėnai (118.2 mm).
