12:00 p.m. | Where you can get sandbags and why you can't get them in Duval County

Sandbags are traditional bulwarks against water flooding into homes and businesses in Jacksonville and beyond during hurricane season.

But while many Northeast Florida county governments are supplying limited numbers of free sandbags and sand, as long as folks fill them themselves, Duval County does not.

The reason is that they don't mix with Jacksonville's drainage system, said Todd Smith, Emergency Preparedness Division chief.

It's impossible not to think of Hurricane Irma as we watch Ian's forecast.

After Irma left Jacksonville with historic-level flooding, journalists Nate Monroe and Christopher Hong investigated the role dredging of the St. Johns River played into what happened in 2017.

As the ocean creeps in: Century of dredging brought wealth, watery risks seen after Hurricane Irma

It's still not clear how close Ian will get to Northeast Florida, but Jacksonville University biologist Quinton White said the risk from flooding has been magnified by river dredging that deepened the shipping channel from the ocean to Jacksonville’s port.

That work, which was completed in May, cleared a path where ocean water will push against the river’s efforts to drain stormwater from the hurricane’s rains.

"If you flooded in Irma, now is the time to take precautions," National Weather Service meteorologist Angie Enyedi said. "... The more vulnerable areas again will be in open areas on the coast and really focused in the St. Johns River basin." — Steve Patterson

6:10 a.m. | Jags prepared for Ian

Jaguars coach Doug Pederson said the team hasn't changed its current practice or travel schedule but are prepared in case the track of Hurricane Ian changes for the worse. The current forecast calls for the area to experience tropical storm-force winds (39 mph or higher) and heavy rain beginning Wednesday night and into Friday.

"Those are things we have to take into consideration," Pederson said. "We've got people in-house that are monitoring that situation for and we'll be prepared either way if we stay and we'll be prepared if we have to move out of here for some reason."

The Jaguars had a road game the last time a hurricane threatened the area, Irma in 2017. They left for Houston, as usual, on a Saturday, but stayed in Houston an extra day until the storm cleared the area. — Garry Smits

6:00 a.m. | Duval Schools will provide update about classes by noon Tuesday

Jacksonville University announced it will close Wednesday through Friday. And Putnam County Public Schools said it was closing schools for the same time period.

Duval County School District officials said Monday they are monitoring the storm closely and will provide an update Tuesday about possible closures.

5:00 a.m. | Jacksonville Mayor Lenny Curry asks residents to prepare

Jacksonville officials are monitoring Hurricane Ian — which is expected to bring high winds and lots of rain — and preparing for the worst.

Residents should also prepare, Mayor Lenny Curry said during a press conference Monday afternoon.

"The biggest threat to our area is excessive rainfall, moderate winds and tornados likely beginning late Wednesday, with the biggest impact happening Thursday," he said. "... While the weather is nice is when you want to check around your home, secure your loose furniture, clean gutters and yard waste and ensure everything is safe and secure."

Earlier Monday, the National Weather Service urged residents to prepare for a "significant storm"

"There's high confidence of tropical storm conditions through Thursday, really ramping up Wednesday night through Thursday," said weather service meteorologist Angie Enyedi. "Then the potential of the tropical storm force winds decreases as we get into and through the day Friday." — Dan Scanlan
