No, I think it's a spot-on reading, judging for other reports. However, I think the wind speed (especially with it being 250°) is being influenced more by the tropical easterly jet rather than 91A.

A second storm right after the first. Arabian Sea and Bay of Bengal are hot spots.

Re: ARABIAN SEA 91A.INVEST
Checking out some observations in the area (I've posted a surface chart below)...
The only ob of great interest comes from a Dutch Cargo Ship, "Nedlloyd Mercator" (PCIM) at 00Z.
PCIM was about 22mi N of 91A at report time. They reported SE winds (140°) at 21KT. 10km visibility with lightning (rainshowers were observed since their last observation, but was not present at time of observation). Temperature was 28.8°C with a dewpoint of 25.7°C. Pressure was 993.3mb. The pressure has dropped, but slightly rebounded since last observation with a net loss of 0.5mb. Clouds were 3/8 stratus fractus, 8/8 altocumulus of a chaotic sky.
