El Temporal de Santa Rosa is scheduled to hit Montevideo on Sunday Night or Monday, August 30-31st -- Right on target. The story goes that Santa Rosa of Peru prayed for a large storm to thwart an impending invasion. Her efforts worked and the storm held off the attack. Although the feast day of Santa Rosa is celebrated on August 30th, the storm has been known to hit this area anywhere from the 25th of August to the 5th of September, bringing rain, high winds and hail.
We have el Temporal de Santa Rosa to thank for the amazing weather here the last few days. Today was 30 degrees Celcius (or 86 Fahrenheit), which is all due to the prevailing weather patterns this time of year, with the hot air from the north colliding with the Antarctic air from the south. Whether the Santa Rosa story of thwarting the enemy was invented because the storm happens to coincide with the saint's feast day, who knows. What we do know is that the storm happens and with some regularity- especially in the last 15 years. In 2005 there was a tremendous Santa Rosa storm where 10 people were killed, many trees were lost and buildings damaged in Uruguay.
There is a thunderstorm forecasted for Sunday night and then possible rain all week through Thursday. While I'm not looking forward to a possible 3+ days and nights of rain that is forecasted, I take this all as a very good sign because el Temporal de Santa Rosa is seen as the start of spring on the Rio de la Plata.
Another recent write up of 'El Temporal' is in this month's issue of Ola Uruguay, a site with some great Uruguay information geared towards investors and retirees.
