Meteorologist Sebastián Pagliarino has warned that weather conditions across Mar del Plata and a large part of the Buenos Aires province are set to deteriorate significantly toward the end of the week. According to an interview on Extra (102.1), a coming ciclogenesis process will trigger varying intensities of rain and storms across the region starting Friday.
Weather Evolution and Wind Shifts in Mar del Plata
The unstable weather follows a week marked by abundant cloudiness, light drizzles, and high humidity throughout the area. Conditions will undergo a brief, temporary transition on Tuesday as wind circulation shifts to the south-southwest. This directional change allows slightly drier and colder air to enter the region, bringing a temporary drop in humidity as the day progresses.
However, this respite will be short-lived. By the second half of the week, the wind is expected to rotate back toward the north and northeast. That shift will draw warm and moist air back into central Argentina, establishing the atmospheric instability needed to spark the upcoming storm system.
Ciclogenesis and Storm Expectations for Friday and Saturday
The core of the severe weather is tied directly to the development of a ciclogenesis event spanning Friday and Saturday. Pagliarino noted that these returning humid conditions create the exact environment required for cold fronts passing through central Argentina to spawn active storms. The resulting system will impact a broad swath of the Buenos Aires province and the Litoral region.
Temperatures during this period will remain relatively mild for the time of year, with maximums hovering between 15 and 16 degrees. Alongside the heavy rains and variable storms, the system could produce strong wave action, particularly affecting coastal areas in the southern zone.
Did You Know? The upcoming weather shift follows a previous strong ciclogenesis event that notably impacted the coastal zone around Mar del Plata with heavy wave action and strong winds.
Potential Meteorological Alerts and Local Forecast
Pagliarino stated that the national meteorological service will likely issue formal weather alerts for the entire region as the storm system solidifies.
Until the significant deterioration arrives, Mar del Plata will experience mostly cloudy skies and persistent humidity with stable temperatures. Tuesday will bring a high of 12 to 13 degrees with light to moderate winds from the south-southwest. Wednesday and Thursday will maintain high humidity levels and maximum temperatures reaching 13 to 14 degrees before conditions worsen sharply on Friday.
Expert Insight: Managing coastal weather risks requires close attention to the interaction between shifting wind patterns and persistent regional humidity. When warm air returns ahead of an approaching front during a developing low-pressure system, rapid atmospheric destabilization makes timely official alerts critical for coastal safety.
