This isn’t just a quick passing shower. The storm will last from Saturday through Monday morning, affecting daily routines for many individuals. Schools, businesses, and outdoor events may need to adjust their plans accordingly. Bad weather conditions will probably impact the entire country during this period.
The good news is that storms like this eventually pass. By Monday morning, conditions should start improving across affected areas. Weather patterns suggest calmer days will return after the system moves through.

Storm Preparation Safety Tips
When is Storm Santa Rosa expected to arrive?
Storm Santa Rosa is forecasted to begin affecting the region starting Saturday afternoon. The weather deterioration will be caused by an extratropical cyclone, with rainfall expected to continue from Saturday through Monday morning. The worst impacts are predicted for Saturday and Sunday evening, so residents should complete their storm preparations by Saturday morning.
Which areas will be most affected by Storm Santa Rosa?
The storm will primarily impact Buenos Aires and the western departments of Uruguay, with specific focus on San José, Canelones, and Montevideo. Northern and coastal regions that are currently experiencing highs of 28°C will see significant weather changes. Bad weather conditions are likely to affect the entire country during the storm period.
How much rainfall should we expect during the storm?
Meteorologists predict rainfall totals of up to 80 millimeters during Storm Santa Rosa. The precipitation will be accompanied by storms, thunderstorms, and strong winds. The heaviest rainfall is anticipated during Saturday and Sunday evening, when the extratropical cyclone will be at its most intense over the affected regions.
What emergency supplies should I prepare for the storm?
Essential storm supplies include non-perishable food for at least three days, bottled water, flashlights, batteries, a battery-powered radio, first aid kit, medications, and phone chargers. Since the storm may cause power outages lasting from Saturday through Monday morning, ensure you have enough supplies to last the entire duration without electricity or access to stores.
How should I prepare my home before Storm Santa Rosa arrives?
Secure outdoor furniture, trim tree branches near your home, check and clean gutters, inspect your roof for loose materials, and ensure windows and doors are properly sealed. Given the expected strong winds and up to 80 millimeters of rainfall, take time to identify potential water entry points and address them before Saturday afternoon when conditions begin to deteriorate.
Should I avoid travel during Storm Santa Rosa?
Travel should be avoided during the storm period, especially on Saturday and Sunday evening when conditions will be most severe. The combination of heavy rainfall, thunderstorms, and strong winds will create dangerous driving conditions. If travel is absolutely necessary, avoid flooded roads and allow extra time for your journey while monitoring weather updates continuously.
When will weather conditions improve after the storm?
Storm effects are expected to subside by Monday morning, with potential for weather improvement after the extratropical cyclone passes through the region. However, residents should continue monitoring meteorological updates for any changes in the forecast. The current Indian summer conditions with temperatures reaching 28°C are expected to return once the storm system moves away.
What should I do if I lose power during the storm?
If power outages occur, avoid using candles due to fire risk and instead rely on flashlights and battery-powered devices. Keep refrigerator and freezer doors closed to maintain temperature, unplug electronic devices to prevent damage from power surges, and never use generators, camp stoves, or charcoal grills indoors. Report outages to your utility company and conserve phone battery for emergencies.
How can I stay informed about Storm Santa Rosa updates?
Monitor local meteorological services, emergency management agencies, and weather radio broadcasts for real-time updates about the extratropical cyclone’s development. Social media channels of official weather services provide frequent updates about storm intensity, timing changes, and safety recommendations. Keep devices charged and have backup power sources available for continuous access to storm information.
What are the signs that I should seek immediate shelter?
Seek immediate shelter when experiencing rapidly intensifying winds, heavy rainfall that reduces visibility, frequent lightning, or tornado warning sirens. During Storm Santa Rosa’s peak intensity on Saturday and Sunday evening, avoid windows, stay in interior rooms on the lowest floor, and be prepared to move to a safe location quickly if conditions worsen beyond the predicted thunderstorms and strong winds.
Post-Storm Recovery Planning

Once Storm Santa Rosa passes through on Monday morning, families and communities will begin the important work of getting back to normal. The first step involves checking everyone’s safety and reaching out to neighbors who might need help. Many individuals will need to clear fallen branches and check for damage around their homes.
Having a simple plan makes everything easier. Keep important phone numbers handy for repairs and insurance. Take pictures of any damage before cleaning up. Remember, working together as a community helps everyone recover faster and stronger than before.
