August 31 (BTA) - The highest temperatures in September
will be between 30 C and 35 C, and the lowest between 3 C and 8
C, higher along the Black Sea coast, the National Institute of
Hydrology and Meteorology reports. The average monthly
temperature is expected to be around the normal, which is 18-21
C in most parts, 15-17 C in the high-altitude plains, and 3-8 C
in the mountains.

Monthly precipitation will be around or slightly above the
normal, at 30-50 l/sq m in the lowlands and 50-80 l/sq m in the
highlands and mountains.

The first ten days of the month will be cool, with widespread
thundery showers spreading from West to East. September 3-4 will
 be a period of relatively settled weather.

September 10-20 will see rising temperatures, close or slightly
higher than the usual ones. It will be mostly sunny during most
of that period. Showers are likely around September 13 and
around September 19-20, when temperatures will drop.

During the last ten days of September temperatures will be
falling slowly. Rain can be expected around September 22, 25 and
 29-30. The first frosts are possible in the high-altitude
plains of Western Bulgaria around September 25-30. DD/BR/LG
