The Current intensity is still 5.5 and the system is still generating sustained winds of about 100 knots. As a forecast tool, the Dvorak technique is showing a weakening trend and the likelihood of a lowering CI within the next 24hours.

德沃夏克分析法（英语： Dvorak Technique ）是由维·德沃夏克（ Vernon Dvorak ）根据多年经验及统计概括后所创下的一项利用地球同步卫星的可见光及红外线卫星云图来评估热带气旋强度的方法。
The Dvorak Technique Explained - dev-east-ospo.woc.noaa.gov
The Dvorak technique is a method using enhanced Infrared and/or visible satellite imagery to quantitatively estimate the intensity of a tropical system. Cloud patterns in satellite imagery normally show an indication of cyclogenesis before the storm reaches tropical storm intensity.
Current Intensity (Cl) Number Rules: 1. Use CI = Final T-no.(FT) except when Final T-no. shows change to weakening trend, or when redevelopment is indicated. 2. For initial weakening, hold CI same for 6* hours, then hold CI 0.5 or 1.0 higher than Final T-no, as storm weakens until the FT has plateaued for >6h. * ref Brown and Franklin (2004 ...

4 天之前 · Once you have a Current Intensity T-Number, you can get an estimate of the wind speed using the Dvorak Current Intensity Chart. The NHC says this on that page: "Note that these are intensity estimates and may be superceded by reconnaissance and/or surface observations." The Dvorak technique has its limitations.
