Miami’s clear, 77-degree start Wednesday is expected to give way to clouds, showers and thunderstorms, according to the forecast information supplied for this report. It calls for a high near 85 and a 50% chance of rain. The same information says a Coastal Flood Statement is in effect through 2 p.m. for coastal Miami-Dade, where high tide could flood some lots, parks and roads and lead to isolated closures.

The supplied forecast details do not identify the issuing weather agency. The statement’s status and the forecast probabilities should therefore be checked against current official weather alerts; no issuing source is independently established here.

Coastal water and heavy rain are different pathways

The Southeast Florida Regional Climate Change Compact’s 2017 Regional Climate Action Plan 2.0 discusses coastal king-tide flooding and inland flooding associated with heavier rainfall as distinct pathways. That distinction helps frame Miami’s separate coastal-flood and storm-rain concerns, but it does not establish what is causing the forecast flooding this week.

Rain chances in the supplied forecast rise to 70% Wednesday night, with a low near 79 and up to a half-inch of additional rainfall possible in some areas. Thursday is forecast to reach about 87, with a 70% chance of showers and thunderstorms. East winds of 16 to 20 mph could gust to 24 mph. The outlook then continues Friday through Tuesday.

A past rain event is context, not a forecast

The Associated Press reported on June 14, 2024, that a separate round of persistent storms had dropped as much as 20 inches of rain in parts of southern Florida; some Miami- and Fort Lauderdale-area streets still had standing water. That episode illustrates the potential for prolonged heavy rain to leave water on urban streets, but it was a different event and does not show that this week’s forecast will produce comparable rainfall or flooding.
