The North American Mesoscale Forecast System (NAM) began running since around 2005. It was replaced by a product known as the Rapid Refresh Forecast System.

Over the past four days, the highest rainfall totaled about 13 to 15 inches between Weston and Sunrise, George Rizzuto, a meteorologist with the National Weather Service in Miami, said Wednesday.

A historic November deluge brought at least 22-30 inches of rain to Florida's east coast, with some locations exceeding NOAA's 1-in-1,000-year rainfall thresholds. As a powerful El Niño develops, the extraordinary flooding raises questions about what lies ahead for Florida's normally drier months.

Cars are nearly submerged, some areas are seeing waist-deep flooding, and schools have been forced to close. And in true Florida fashion, some residents are even using kayaks and paddleboards to get around, or joking about pulling their airboat off their trailer.

Some areas have already received 3 to 6 inches of rain, others over a foot, and another 1 to 3 inches could fall before conditions gradually improve Tuesday.

A developing storm system is bringing rounds of heavy rainfall to South Florida. Dangerous surf, rip currents and coastal flooding could be problematic along Atlantic beaches.

Historic king tides sent saltwater surging over seawalls and into neighborhoods, flooding major roads and bridges. Some of the water levels rivaled some recorded during past hurricanes.

Halloween weekend will bring a little bit of everything to the Sunshine State, from warm temperatures and occasional sunshine to gusty coastal winds and increasing chances for rain and thunderstorms.

As daylight saving time ends in Florida, much of the country will enter what is known as standard time, which results in earlier sunrises and earlier sunsets.

Nor'easters typically occur during the fall and winter months, when cold continental air clashes with warm, moist air from the Gulf and the Atlantic Ocean.

Dangerous surf, rip currents, coastal flooding, beach erosion and strong northeast winds are expected to continue along Florida’s east coast through the week.

Hurricane forecasters are increasingly using artificial intelligence to make predictions.
