Earthquake-ravaged Haiti is bracing itself for another natural disaster as Tropical Storm Emily brushed past Puerto Rico to set its sights on the struggling island nation.

The storm comes roughly a year and a half after a massive, deadly quake left more than 600,000 Haitians homeless.

Emily is expected to hit Wednesday afternoon, bringing with it a steady shield of rain, according to Accuweather.com senior meteorologist John Dlugoensk.

"The biggest threat to lives is probably the flooding," Dlugoenski said.  Authorities are working to move people out of high-risk areas ahead of time. Many fear a deluge could reverse months of recovery and re-building.

Father Yves Geffard, pastor at Notre Dame Catholic Mission in Florida, is helping to re-build a church in Haiti hit hard by last year's earthquake.

"When I went there I can't say there's much progress, not much improvement," he said.

Geffard is praying for the people of Haiti as Emily inches closer. He was in Haiti just two weeks ago delivering medical supplies and food and says the nation is still very vulnerable.

"The situation almost the same -- people still under the tents, people still begging for food," Geffard said.  "It's really a chaotic situation."

Geffard's congregation hopes to make a difference in the quake-battered country by praying and digging deep to financially support the resilient nation.

"Despite all these turmoil's -- hurricanes, earthquakes -- they believe God has a plan for Haiti," Geffard

The tropical storm will likely pass through Haiti this afternoon. Computer models show Emily could hit Florida later this week.
