A red alert, the highest level of warning, is in force for heavy rain in the regions of Varna, Dobrich, Smolyan, Kardzhali and Haskovo. Another 60 litres or more per square metre could fall there.
The rain comes from a Mediterranean cyclone moving across the Balkans. There is a risk of floods across Bulgaria over the next 24 hours. The Black Sea coast will see long, heavy rain and a strong north-east wind.
Elsewhere the wind is moderate, but it is strong in the east. Highs will be between 7C and 12C, and about 8C in Sofia. It will be a little warmer by the sea, up to 15-16C.
The wind is strong in the mountains and precipitation is heavy. The snow line drops to about 1,500 metres above sea level. Highs in the ski resorts are still above zero: 1C at Aleko and Malyovitsa, 6C in Borovets and about 8C in Bansko and Smolyan.
On Wednesday the rain will stop in most of Bulgaria and the wind will ease. The east will stay windy, with more heavy rain.
From Thursday the rain will stop everywhere. The day will be mostly cloudy, with light, scattered showers, mainly in the west.
Friday and Saturday will be very sunny, with morning fog in places. Lows will fall, dipping below zero in some places. Highs on Friday will be a little higher, between 9C and 14C, and will stay almost the same on the other days.
On 2 November we reported that Burgas was under an orange alert for heavy rain, along with Varna, Dobrich and four more regions in eastern Bulgaria. The warning was based on data from the National Institute of Meteorology and Hydrology.
Almost everywhere in the Balkans has yellow, orange or red alerts for heavy rain tomorrow, according to the forecast. Greece expects thunderstorms, which are unusual for the season, and heavy rain is falling over the Apennines for another day. Most of Europe lies under a broad area of high pressure, with almost no rain and morning fog in places. In the afternoon there will be showers and thunder on Spain's east coast.
