ED's post explained the upgrade of Tropical Depression to Tropical Storm. Present satellite technology and positioning allow TPC/NHC to classify and declassify Tropical Systems that would have been unobserved in past decades. Gamma, is presently maintaining a Current Intensity (CI) of 3.0 AODT (Dvorak), from CIMSS, with winds estimated at 45kts and pressure estimated at 1000mb. However, the Raw Value has dropped from a 3.4 CI at 1945Z to a 1.9 CI at 0115Z. The 'Final AODT Position' is estimated near the half-way point between the heaviest convection and the Honduran Coast.
I recall NHC stating yesterday, that the aircraft couldn't close of a Low. They used surface reports from near-storm locations of 45-60mph winds as additional evidence of a Tropical Storm.
Below are two examples of how a Low is "closed".
The "Delta" pattern is one of the flight that RECON utilizes to "close off" a Low. The storm may be entered at any of the 'turn points' and the remaining pattern is flown to close off the wind speed and direction.
