Mathew eye wall replacement could cause some decrease in strength.

The phenomena of most interest right now is the state of Matthew’s inner eye wall. Yesterday it was a bit ragged but now it has become quite compact and well structured (top image). As the pressure
has fallen, the eye wall has shrunk and is now about 20 miles in diameter. In the meantime, an outer band is forming rapidly further from the center. This may signal the development of
a secondary, or replacement, eye wall. The latest Hurricane Hunter observations, second image – blue line, does show a secondary peak in wind speed.
Hurricane intensity tends to weaken during an eye wall replacement cycle but Matthew is so close to FL at this point that it may not occur prior to close approach tonight.
