IMGW issues level I dense fog warnings for parts of ten Polish voivodeships

Warning area and timing

The Institute of Meteorology and Water Management (IMGW) has issued level I meteorological warnings for dense fog covering parts of ten voivodeships. The area includes Łódź Voivodeship and sections of the Pomeranian, Warmian-Masurian, Kuyavian-Pomeranian, Masovian, Świętokrzyskie, Lower Silesian, Silesian, Lesser Poland and Subcarpathian voivodeships. The alerts can take effect on Wednesday, 28 October, from 17:00 at the earliest, and are expected to expire at 10:00 on Thursday, 29 October. The warning text says dangerous conditions could appear as early as the afternoon of Wednesday, 28 October. Locally, visibility could fall below 200 metres during that period.

Conditions on the roads

Forecasters expect the dense fog to significantly limit visibility, and the forecast urges drivers to exercise particular caution. Drivers are advised to adjust their speed to the road conditions and to increase the distance from the vehicles ahead. Fog is forecast for the morning of Wednesday, 28 October, in many areas, particularly in the east and southeast, where visibility may drop below 200 metres. Fog is expected to return in many places overnight from Wednesday, 28 October, into Thursday, 29 October. The conditions are therefore likely to affect the morning commute on both days.

Weather through Wednesday

Cloud cover is forecast to be large across most of the country on Wednesday, 28 October, with brighter spells in places. Upper Silesia is the exception, where skies should remain mostly low to moderately cloudy. Weak rain is expected to move slowly from west to east during the day, with light rain or drizzle locally in the east and southeast. Daytime highs are forecast between 10 and 14 degrees Celsius, falling to about 8 degrees in the northwest, the west and the foothills of the Carpathians. Winds are mostly weak and moderate at times on the coast, blowing initially from the south before turning northwest and west in the west during the day. Warsaw's pressure at noon is forecast at 1011 hPa, with steady pressure expected. One report cited temperatures from minus 2 degrees Celsius in Kłodzko to 10 degrees in Świnoujście.

Night and Thursday

Overnight, cloud cover stays large with occasional brighter spells, and weak rain or drizzle may fall mainly along a belt from Pomerania through Kuyavia and Greater Poland to Lower Silesia. Minimum temperatures are forecast between 4 and 8 degrees Celsius, dropping to between minus 1 and minus 2 degrees on the Podhale. Gusts in the higher Sudetes could reach 60 km/h. On Thursday, 29 October, cloud cover remains large, with larger breaks in the north and west and weak rain or drizzle in places. Sleet is possible on the peaks of the Silesian and Żywiec Beskids, and light snow is possible in the Tatras above 1,800 metres above sea level. Daytime highs of 8 to 12 degrees Celsius are forecast for Thursday, 29 October, and fog is expected to return in the morning, limiting visibility to 200 metres in places.
