Hurricane Ike is a dangerous Category 4 storm as it continues to close in eastern Cuba. Meanwhile, Tropical Rainstorm Hanna is moving through Atlantic Canada today after lashing the Eastern Seaboard on Saturday.

The AccuWeather.com Hurricane Center reports that Ike remains a Category 4 hurricane this afternoon just under 100 miles east-northeast of Guantanamo, Cuba, with sustained winds near 135 mph.

All interests in Florida and along the Gulf Coast should be monitoring the movement of this potentially devastating storm.

The track of Ike will be influenced by the strength and position of an area of high pressure to the north of the storm. Today, Ike pummels the islands of the northern Caribbean with torrential rainfall and a storm surge up to 18 feet.

On Monday, outer bands of wind and rain, strong surf and rip currents will reach the Southeast coast. Ike is forecast to weaken to Category 2 strength after making landfall on Monday over the northern coast of Cuba.

According to Fox News Channel, officials in the Florida Keys planned to start a phased evacuation for residents this morning after telling visitors to leave on Saturday.

After battering Cuba, Ike is forecast to move through the Straits of Florida and into the Gulf of Mexico. This is not the news Gulf Coast residents and officials want to hear after dealing with Hurricane Gustav.

Louisiana Gov. Bobby Jindal set up a task force to prepare for the possibility of more havoc. "We're not hoping for another strike, another storm, but we're ready," he said. New Orleans Mayor Ray Nagin said city officials are monitoring Ike as residents continue to return after being evacuated ahead of Hurricane Gustav.

Ike overnight roared across the Turks and Caicos island chain. Last week, Hanna pounded the low-lying islands as it spun nearly stationary for four days. Many residents and tourists left the islands, while those that remained huddled in shelters on Saturday.

In Haiti, authorities tried to move thousands of people into shelters ahead of Ike, while struggling to recover from devastation caused by Hanna. Rescue workers fear the death toll could rise into the hundreds in the flooded city of Gonaives.

Hanna will bring heavy rain to New Brunswick and Nova Scotia today, while sunshine and dry conditions return after the storm raced up the Eastern Seaboard on Saturday.

The Severe Weather Center reports that all tropical storm warnings have been discontinued in the U.S. Flood-related watches and warnings are still in effect in eastern New England.

The Atlantic Storm Prediction Centre of Canada has issued rainfall warnings for the Canadian Maritimes. Southern New Brunswick and western Nova Scotia could receive 1 to 3 inches (40 to 80 mm) of rain with locally higher amounts. Flash flooding could result with the heavy rainfall.

Hanna made landfall early on Saturday along the border of North and South Carolina with winds of 70 mph. Flooding affected many cities of the East, including Washington, D.C., and Charleston, S.C.

Rain totals through 2 a.m. EDT Sunday include:

• East Hartford, Conn.: 6.19 inches
• New York City LaGuardia: 3.21 inches
• Atlantic City, N.J.: 2.89 inches
• Philadelphia, Pa.: 2.25 inches
• Washington, D.C. (Dulles Airport): 5.41 inches
• Woodbridge, Va.: 8.35 inches
• Fayetteville, N.C.: 4.62 inches
• Myrtle Beach, S.C.: 4.41 inches

Gusty winds toppled trees and downed power lines as Hanna pushed up the I-95 corridor. According to the Associated Press, 100,000 customers were without power on Saturday at noon. A possible tornado damaged cars and houses in Allentown, Pa.

Among the strongest wind gusts from Hanna:

• Wrightsville Beach, N.C.: 72 mph
• Wilmington, N.C.: 54 mph
• North Myrtle Beach, N.C.: 53 mph
• Annapolis, Md.: 54 mph
• North Wildwood, N.J.: 51 mph

Amtrak canceled some Saturday services along the East Coast, while gusty winds caused cancellations at major airports, including Raleigh-Durham and Dulles International.

Hanna washed out play on Saturday at the U.S. Open Tennis Championship in New York City. The Men's Semifinal and Women's Final were rescheduled for today. The Men's Singles Final is rescheduled for Monday at 5:00 p.m. EDT.

NASCAR was forced to reschedule the race in Richmond, Va., to today. Rain in Philadelphia on Saturday washed out the game between the Phillies and the New York Mets.

The combination of Hanna and the pending arrival of Hurricane Ike forced NASA to delay the launch of the Space Shuttle Atlantis on the final mission to the Hubble Space Telescope.

Atlantis was moved on Thursday from the Vehicle Assembly Building to its launch pad at the Kennedy Space Center. NASA officials said Friday the target launch date was pushed back two days to September 10, and more delays are possible.
