Intenzivní sněžení v oblasti Jihomoravského kraje

Od rána 7 hod. do 19 hod (23.2.2013) na celém území ČR napadlo většinou od 5 do 15 cm, na horách i více. Nejvíc nového sněhu napadlo v Olomouckém, Jihomoravském a Středočeském kraji. Luká v Olomouckém kraji měla až 16 cm nového sněhu, Ostrava a Brno 9 cm, Praha 11 cm. Nejvyšší hodinová intenzita sněžení byla v dopoledních hodinách v maximálních hodnotách od 1 do 4 cm.

Tropical Depression 02W (Northwestern Pacific Ocean)

The second tropical depression of the northwestern Pacific Ocean season formed on Feb. 19, and NASA's Aqua satellite showed the storm was soaking the central and southern Philippines. NASA's Aqua satellite passed over Tropical Depression 02W (TD02W) as it was coming together and soaking provinces in Mindanao and the Palawan province of Luzon. The Atmospheric Infrared Sounder (AIRS) instrument that flies aboard Aqua captured an infrared image of the depression at 0541 UTC (12:41 a.m. EST). The AIRS image showed very cold cloud top temperatures, colder than -63F (-52C) over Mindanao and stretching west to Palawan. Cloud top temperatures that cold are indicative of the potential to drop heavy rainfall. AIRS infrared satellite imagery showed a very poorly organized and ill- defined low-level circulation center. The convection (rising air that forms thunderstorms that make up the depression) appears disorganized in the northern quadrant of the storm. On Feb. 19 at 0900 UTC, the low pressure area designated as System 98W organized into a tropical depression and was renamed "02W." Tropical Depression 02W formed south of Mindanao, the Philippines. TD02W is referred to locally in the Philippines as "Tropical Depression Crising."As a result of the formation of the depression, warnings were posted by PAGASA for many areas in the Philippines. Public storm warning signal #1 was posted for the following provinces of Mindanao: Davao del Norte and Sur and Oriental, Samal Island, Compostela Valley, the southern part of Surigao del Sur, Agusan del Sur, Bukidnon, Lanao del Norte and Sur, North Cotabato, Maguindanao, Sultan Kudarat, South Cotabato, Sarangani, Misamis Occidental, Zamboanga del Norte and Sur and& Sibugay, Basilan, Sulu and Tawi-Tawi. In addition, Signal #1 is now in effect for the south of the Palawan province of Luzon.On Feb. 19 at 1500 UTC (10 a.m. EST), TD02W had maximum sustained winds near 25 knots (28.7 mph/46.3 kph). TD02W was located near 6.5 north latitude and 122.9 east longitude, just 55 nautical miles (63.3 miles/102 km) east-southeast of Zamboanga, Philippines. RD02W is moving to the west-northwest at 9 knots (10.3 mph/16.6 kph). TD02W is currently experiencing moderate vertical wind shear, as high as 20 knots (23 mph/37 kph) which is keeping the depression from getting better organized. That is expected to change, however, once TD02W moves west into the South China Sea.Forecasters at the Joint Typhoon Warning Center expect TD02W to move to the west-northwest, and pass just south of Palawan's southern tip before moving into open waters of the South China Sea where it is expected to become more organized.

Tropical Storm Haruna (Southern Indian Ocean)

Tropical Storm Haruna came together on Feb. 19 in the Southern Indian Ocean and two NASA satellites provided visible and infrared imagery that helped forecasters see the system's organization. A low pressure area called System 94S developed on Friday, Feb. 15 in the northern Mozambique Channel. Over the course of four days System 94S became more organized and by Feb. 19 it became Tropical Storm Haruna. On Tuesday, Feb. 19, Tropical Storm Haruna had maximum sustained winds near 35 knots (40.2 mph/64.8 kph). Haruna was located in the Mozambique Channel, near 21.4 south latitude and 40.9 east longitude, about 375 nautical miles (431.5 miles/694.5 km) west-southwest of Antananarivo, Madagascar. Microwave satellite imagery from the AMSU-B instrument confirmed the location of Haruna's low-level center. Haruna is moving south at 5 knots (5.7 mph/9.2 kph). Infrared imagery from NASA's Atmospheric Infrared Sounder (AIRS) instrument taken on Feb. 18 and Feb. 19 showed the development of Haruna from a depression into a tropical storm. AIRS imagery on Feb. 19 indicated that the low-level circulation center was well-defined and symmetrical. The area of strongest thunderstorms appeared around the center of circulation and in a band of thunderstorms around the south and east of the center where cloud top temperatures were colder than -63F (-52C). The AIRS data on Feb. 19 also showed that the band of thunderstorms east of the center became fragmented over eastern Madagascar. An instrument aboard NASA's Terra satellite called the Moderate Resolution Imaging Spectroradiometer, also known as "MODIS" captured a visible image of Tropical Storm Haruna on Feb. 19 at 0745 UTC (2:45 a.m. EST). The image showed the center of Haruna over the southern Mozambique Channel, between Mozambique on the African mainland to the west, and the island nation of Madagascar east. Haruna's eastern bands of thunderstorms were draped over Madagascar bringing showers, thunderstorms and gusty winds to the island. The MODIS image was created by the MODIS Rapid Response Team at NASA's Goddard Space Flight Center in Greenbelt, Md. According to forecasters at the Joint Typhoon Warning Center (JTWC), the organization that forecasts tropical cyclones in the Indian Ocean, Haruna is being guided by a low-to-mid-level subtropical ridge (elongated area) of high pressure and is expected to continue moving south until a low pressure area turns the tropical storm southeast. Forecasters at the JTWC expect that Haruna will intensify over the next day or two and make a brief landfall over southern Madagascar. Haruna is expected to re-emerge into open ocean and vertical wind shear is forecast to increase with the low pressure area, weakening the storm.
