Florida is preparing for a week of relentless rainfall, with predictions of up to 12 inches in some cities, which could lead to widespread flooding across the state. The deluge of tropical moisture is the result of a collaboration between high- and low-pressure systems, acting as a channel to funnel moisture over Florida.

According to FOX Weather Meteorologist Kiyana Lewis, an area of low pressure over Mexico and an area of high pressure over the Atlantic will remain stationary throughout the week, allowing tropical moisture to move northward into the Gulf of Mexico. As a result of a drop in the jet stream, the majority of this moisture will be filtered over Florida.

The heavy rains are expected to bring relief from scorching temperatures and triple-digit heat indices that plagued the region over the weekend. While South Florida will see temperatures in the 80s by Sunday, it may take a few more days for the cooler weather to reach the rest of the state.

Central Florida is projected to experience high temperatures in the upper 80s by Wednesday, although the heat index in Orlando will remain in the mid-90s due to high humidity. Jacksonville, which reached a forecast high of 100 degrees on Monday, will welcome temperatures in the 80s by Wednesday.

The most significant rainfall is anticipated from Tuesday through Thursday, presenting the risk of flooding as accumulated rainfall totals increase. Miami and Fort Lauderdale could receive between 8 and 12 inches of rain throughout the week, while Orlando is expected to see 3-5 inches, with Thursday having the highest rainfall totals. In northern Florida, from Jacksonville to St. Augustine, 1-2 inches of rain are likely.

The threat of flash flooding is currently low but could quickly escalate, especially in urban areas prone to flooding and as the ground becomes saturated with daily rainfall. Lewis warns that the rich moisture content could continue to produce tropical downpours in the latter half of the week, posing a greater risk for flash flooding.

However, amidst the concern for potential flooding, the heavy rainfall brings hope for addressing Florida's ongoing drought situation. Half of the state currently faces some level of drought after experiencing a dry April and May. Southwest Florida, particularly Fort Myers and Naples, currently under Severe Drought, is expected to benefit the most from the anticipated rainfall. Tampa could also receive between 5 and 8 inches.

It is not uncommon for Florida to experience a drier April and May before the rainy season starts in mid-May, leading up to the Atlantic hurricane season beginning in June. Historical weather data from the National Weather Service reveals that June typically sees the highest average rainfall in Miami, with an average of 10.51 inches.

As Florida prepares for heavy rainfall and potential flooding, residents are advised to stay updated on weather forecasts, make necessary preparations to prevent damage, and take precautions to ensure their safety during this period of intense rainfall.
