MIAMI (AP) — The Latest on Hurricane Michael (all times local):

3:45 p.m.

Florida Gov. Rick Scott says Hurricane Michael is a "monstrous storm" that has the potential to be devastating to the Florida Panhandle.

Speaking alongside emergency officials in Pasco County, Scott said Monday he's waiving tolls. He also has declared a state of emergency for 35 counties and asked President Donald Trump for assistance ahead of the storm.

The governor warns that storm surge could be as high as 8-10 feet (2.4-3 meters) in some parts of the Panhandle and 2-4 feet (0.6-1.2 meters) in the Tampa Bay area. Scott is urging people along the Gulf Coast to finish their storm preparations Monday evening.

3 p.m.

Three Florida Panhandle counties have issued mandatory evacuation orders ahead of Hurricane Michael's expected landfall.

Residents of barrier islands, mobile homes and low-lying coastal areas in Gulf, Wakulla and Bay counties were ordered to evacuate by late Monday or early Tuesday.

In a Facebook post Monday, the Wakulla County Sheriff's Office said no shelters would be open in Wakulla County because Michael was forecast to become a major hurricane with winds topping 111 mph (178 kph).

The sheriff's office says Wakulla County shelters were rated safe only for hurricanes below that threshold. Residents are being urged to evacuate inland. The sheriff's office says Michael "has the potential to be a historic storm — please take heed."

2 p.m.

Hurricane Michael is lashing the western tip of Cuba with heavy rainfall and strong winds.

The National Hurricane Center in Miami says Michael's top sustained winds were around 75 mph (120 kph). The storm was moving north around 7 mph (11 kph).

The storm was centered about 20 miles (30 kilometers) off the western tip of Cuba, and about 145 miles (230 kilometers) east-northeast of Cozumel, Mexico.

Forecasters say Michael will move into very warm waters in the Gulf of Mexico. It could strengthen into a major hurricane with winds topping 111 mph (178 kph) before an expected strike Wednesday on Florida's Panhandle.

Meanwhile, long-lived Tropical Storm Leslie was expected to gradually strengthen over the Atlantic Ocean but was no threat to the U.S. coastline.

Michael has become a hurricane as the storm gets ready to move into the Gulf of Mexico.

Forecasters at the National Hurricane Center in Miami say Michael will move over very warm waters and could strengthen into a major hurricane with winds topping 111 mph (178 kph) by Tuesday night.

Michael was lashing western Cuba late Monday morning with heavy rains and strong winds.

According to the hurricane center, Michael's top sustained winds were around 75 mph (120 kph). The storm was moving north around 7 mph (11 kph).

The storm was centered about 50 miles (80 kilometers) off the western tip of Cuba, and about 140 miles (220 kilometers) east-northeast of Cozumel, Mexico.

Michael is forecast to make landfall by midweek in Florida's Panhandle or Big Bend.

10 a.m.

The director of the National Hurricane Center says Florida's Big Bend could see up to 11 feet (3.35 meters) of storm surge after Tropical Storm Michael strengthens into a hurricane over the warm waters of the Gulf of Mexico.

Ken Graham says the storm's large size, strong winds and heavy rains could produce a lot of flooding, and the shape of this stretch of coastline makes it particularly vulnerable to storm surge.

Water being forced on shore by the storm could get trapped in estuaries and rivers and pushed inland.

According to the forecast, parts of the Tampa Bay area and the western Florida Panhandle also could see up to 4 feet (1.2 meters) of storm surge.

Midnight

A tropical storm that rapidly formed southwest of Cuba could become a dangerous Category 2 hurricane by the time of an expected midweek landfall on the Gulf Coast in the Florida Panhandle.

Florida Gov. Rick Scott has issued an order for a state of emergency for 26 counties to rush preparations in the Florida Panhandle and the Big Bend area, freeing up resources and activating 500 members of the Florida National Guard. Scott says: "This storm will be life-threatening and extremely dangerous."

Michael became a tropical storm on Sunday with sustained winds of up to 50 mph (85 kph). But it rapidly intensified, and its top winds clocked in at 60 mph (95 kph) by late Sunday evening. The storm is expected to gain hurricane status by Monday night or Tuesday as its core slowly crawls into the Gulf of Mexico, nearing the Florida Panhandle coast around midweek.
