PM Update: Scattered showers and thunderstorms through the early evening. Much cooler on Monday. You may have to dodge some raindrops through about 8 tonight. A cold front moves through tomorrow morning and ushers in much more seasonable weather.
Only cook live crabs, because they deteriorate very quickly after they have expired. You can simply throw the crabs in a pot of boiling water to cook them. Depending on the size of the crabs, it will take between 6 and 10 minutes for them to cook thoroughly. If the crab is alive when you start, the amount of cooking time has very little to do with safety  it s more a question of whether the meat is underdone, overdone, or cooked just right.
Bring the water back to a boil and cook until the crabs start to float. Depending on the size of the crabs, this will happen in 10 to 15 minutes or so. Use tongs to remove the crabs and set them out until cool enough to handle.ut the crabs in a steamer basket or insert, or simply pile them into the pot and let the bottom crab or two boil slightly and act as a platform for the other crabs to steam. Cook 10 to 20 minutes, depending on the size of the crabs.
