Solution:

• Turn the Heat Off - Don't try to move the pot. You might accidentally splash yourself or your kitchen with burning oil. And that would be bad.

• Cover the Pot with a Metal Lid - Fire cannot exist in the absence of oxygen. With the lid on (and the heat off), the fire should quickly consume all the oxygen and put itself out. Use a metal lid since glass will shatter.

• Pour on Baking Soda - Baking soda will extinguish grease fires, but only if they're small. It takes a lot of baking soda to do the job.

• Spray the Pot with a Class B Dry Chemical Fire Extinguisher - This is your last resort, as fire extinguishers will contaminate your kitchen. Still, it's better than the alternative if the fire is getting out of control.

• Get Out and Call 911 - If the fire does break out of control, don't try to be a hero. Get out and find a phone to call 911.

Whatever you do, DO NOT do the following:

• Do Not Use Water - Pouring water can cause the oil to splash and spread the fire. The vaporizing water can also carry grease particles in it, also spreading the fire.

• Do Not Move the Pot or Carry It Outside - Throwing the pot outside might seem logical in the frenzy of the moment. But trying to move the pot might splash burning oil on you, your home, and anything outside.  

• Do Not Throw Any Other Baking Product On the Fire - Flour might look like baking soda, but it won't react the same. Only baking soda can help put out a grease fire.

Eddi Din [679]
      Latitude 12 N, Longitude 45 W is in the North Atlantic Ocean. This is the region where tropical cyclones ( hurricanes ) can start. Hurricanes are large tropical storms with heavy winds. They form only over warm ocean waters near the Equator.
      There are 6 main requirements for formation of a hurricane:
      - warm sea surface temperature,
      - atmospheric instability,
      - high humidity in the lower to middle level of the troposphere,
      - enough Coriolis force to develop a low pressure center,
      - a preexisting low level focus or disturbance,
      - low vertical wind sheer.
       Answer:
      Those are favorable conditions for a hurricane but you also need other factors.
