Hurricane Irma on September 5.

Hurricane Irma became a dangerous Category 5 storm with wind speeds of 175 miles per hour. The hurricane was headed toward Florida, but what are the chances it could hit Port Lucie?

Irma was headed toward Puerto Rico and the Virgin Islands on September 5. Tropical Storm conditions are possible in St. Lucie on Saturday, according to September 4 weather forecasts for the area. Right now, the storm is predicted to cut a swath through southern Florida, including Miami and Key West. The closest approach to central Florida from the storm is expected to come on Sunday. The Florida governor has declared a state of emergency.

The hazardous weather outlook for east central Florida, including Port St. Lucie, and as of September 5 reads: For September 5: “Isolated lightning storms are forecast to develop near the coast as the Atlantic sea breeze pushes inland early this afternoon. Storm coverage will increase over the interior counties from mid to late afternoon as the sea breeze begins to interact with other boundaries. A few storms could become strong with winds gusts of 40 to 50 mph, frequent cloud to ground lightning strikes, and very heavy rainfall the primary weather hazards. Locally heavy rain in slow moving storms will be possible this afternoon, especially across the inland counties. Rainfall amounts between 2 and 3 inches in a short time period will produce ponding of water on roadways and flooding in poor drainage areas. A long period swell will maintain a moderate risk for dangerous rip currents at area beaches today. Check with local beach patrol before entering the water and never swim alone!”

The outlook continues: “DAYS TWO THROUGH SEVEN…WEDNESDAY THROUGH MONDAY. Shower and thunderstorm chances will increase to above normal from Wednesday onward as an early season cool front sags into north Florida and stalls. The forecast for this weekend remains somewhat uncertain as Major Hurricane Irma moves into the Florida Straits and makes its closest approach to central Florida, probably around Sunday. While it is still too early to be specific about any direct impacts that Irma will have on east central Florida, there is an increasing likelihood of as least some impact from the system. Increasing rain chances and increasingly windy conditions are likely this weekend, and boating and surf conditions are expected to become increasingly hazardous by late week, and dangerous by this weekend.”

Here’s the Port St. Lucie forecast:

The storm remains unpredictable.

“Hurricane Center and National Weather Service forecasters warned it’s too soon to tell what Irma’s impacts could be in Florida or other hurricane-prone areas of the United States,” Gainesville.com reported. “Forecasters must wait to see if Irma takes a predicted turn to the north as it travels around a high-pressure ridge over the Atlantic Ocean and see how the ridge and hurricane interact with a trough moving across the U.S.”

See the weather forecast page for St. Lucie here. Be aware that St. Lucie’s weather is tracked out of the Melbourne, Florida office of the National Weather Service.

Here’s the projected path of the storm as of September 5:
