12/24/2022 0 Comments Hurricane matthew where is it nowTyphoon Sudal (below) is a good example of a typical Pacific eyewall replacement cycle. Some storms can undergo several cycles over a life span.ĭouble eyewall structures are more common in West Pacific storms because they general encounter more favorable conditions for intensification (less land, warm water and less wind shear). The eyewall replacement cycle for Matthew is happening over a time span of 6 to 18 hours, but they can take up 2 to 3 days. With Matthew it could end up meaning slightly lower (but still Category 4 winds) but over a broader area (which means parts of Florida may experience hurricane force winds sooner). The presence of concentric eyewalls is a very interesting "Jekyll and Hyde" transition process in TCs. If so, some weakening could occur, but there could also be fluctuations in intensity while the hurricane moves toward the east coast of Florida. Matthew was briefly classified as a Category Five hurricane on Friday, earning it a spot as one of the more powerful storms to form in a very long time. There some indications that an outer eyewall is trying to form, and perhaps an eyewall cycle will occur. Until the plane finishes sampling the circulation, the initial intensity is kept at 120 kt. A NOAA Hurricane Hunter plane just reached Matthew and measured 121 kt at the 700-mb level and a minimum pressure of 936 mb.
