Satellite images show Hurricane Joaquin becoming a powerful Category 4 storm over the Atlantic Ocean. The hurricane is packing maximum sustained winds of 130 mph and is expected to strengthen further as it moves away from the Bahamas and toward Bermuda.

Hurricane Joaquin is the strongest storm to hit the Atlantic Ocean this season. The storm has already caused widespread damage in the Bahamas, where it knocked out power and flooded streets. Joaquin is expected to bring heavy rains and high winds to Bermuda as it passes by the island nation.

The hurricane is also expected to produce large swells that could affect the East Coast of the United States. Forecasters say the swells could produce dangerous rip currents and coastal erosion.

Hurricane Joaquin is a reminder that the Atlantic hurricane season is still active. The season officially ends on November 30, but storms can form after that date.
