Miami, FL – Miami faces a stretch of increasingly wet and windy weather beginning Saturday, with rain chances climbing to 90% Sunday as stronger easterly winds bring gusts approaching 40 mph.
According to the National Weather Service in Miami, showers and thunderstorms become more likely Saturday afternoon before a wetter pattern develops Sunday and continues into early next week. The forecast calls for several consecutive days with elevated rain chances across Miami, although conditions elsewhere in South Florida may differ.
The shift comes after several days of temperatures in the upper 80s, with daytime highs easing slightly as rain chances increase.

Northeast winds of 7 to 15 mph could gust as high as 21 mph during the day.

Sunday brings the most significant wind increase in the supplied forecast.
East winds are expected around 25 mph, with gusts as high as 37 mph. Showers and possibly a thunderstorm are forecast, with precipitation chances reaching 90%.

Despite the wetter pattern, daytime temperatures should remain in the mid 80s, while overnight lows hold in the upper 70s.
