All eyes are on Hurricane Florence and its path toward the Carolinas, but several other hurricanes are brewing as well.
Where is the hurricane now?
As of 5 a.m., Florence was centred about 625 miles southeast of Bermuda, moving west at 9 miles per hour.
Forecasters said early Monday afternoon that data indicated Florence has maximum sustained winds near 130 miles per hour and a minimum central pressure of 946 millibars (27.93 inches).
As of 12 p.m. on Monday, Florence is now a Category 4 hurricane.
Some strengthening is expected during the next 36 hours, and Florence is expected to be an extremely risky major hurricane through Thursday.
What else should I know?

Florence is being felt along the North Carolina coast with large sea swells.
At a press conference on Monday, Cooper called his state the "bullseye" for Hurricane Florence, saying they are "bracing for a hard hit". While the exact track of Florence remains uncertain, the threat of a North Carolina landfall sometime Thursday into Friday continues to increase. The center said the powerful waves are likely to cause life-threatening surf and rip current conditions.
