Hurricane Matthew slightly grew stronger early Tuesday and shifted closer to Florida, according to the National Hurricane Center in Miami.

"The threat to Florida and the southeastern U.S. coast has increased," the National Hurricane Center said. Life-threatening rain and storm surge was expected in parts of Haiti by early Tuesday morning.

The updated forecast tracked Matthew heading west closer to Florida, which also is in a state of emergency. Matthew is expected to reach Florida later this week.

Write or review your Family Emergency Plan: Before an emergency happens, sit down with your family or close friends and decide how you will get in contact with each other, where you will go and what you will do in an emergency. Keep a copy of this plan in your emergency supplies kit or another safe place where you can access it in the event of a disaster.

Put Together an Emergency Supplies Kit: Put together a basic disaster supplies kit and consider storage locations for different situations. Check emergency equipment, such as flashlights, generators and storm shutters.

Review Your Home Owners Insurance: Review your insurance policy to ensure that you have adequate coverage for your home.
