Key Factors
- 01 Chance of showers and thunderstorms increases through the day, reaching about 52–60% precipitation probability from 18:00–22:00 (local -04:00).
- 02 Storm risk is specifically noted as potentially severe with heavy rain in the afternoon/evening period (daily forecast).
- 03 From 18:00–05:00, showers and thunderstorms are likely and some storms could produce heavy rain (daily forecast).
- 04 No visibility data is provided, and heavy rain/t-storms can rapidly reduce visibility even if not explicitly listed.

Recommendation
Drive in the morning only during the lower-risk window: 07:00–10:00 (-04:00), when precipitation chances are ~16–20% and storms are only a slight chance. For the evening, avoid the peak storm period; if you must travel, choose the later window 21:00–22:00, when precipitation probability begins to ease (about 55% to 49%)—still expect thunderstorms and heavy rain potential.
