sudestada A strong SE wind (Sudestada) which develops when depressions from the Parana basin deepen rapidly near the coast before moving SE over the sea. Occasionally the wind reaches gale force with rough seas, rain, and bad visibility. During one of these storms in July, 1923, the SE wind aver- aged 62 knots over an hour and reached 86 knots in gusts. Be- tween 5 and 8 Sudestadas occur each year. Sudestadas may develop during relatively high pressure with an average frequency of 3 per year at Montevideo. These SE winds may persist for a day or two to cause heavy seas and an appreciable rise the level of the Rio de la Plata. See related discussion under pampero.
