Must be something else

I decided to look at the raw FTP file listing and the NHC server is as it should be.
"-rw-r--r-- 1 ftp ftp 3721 Sep 01 00:40 invest_al942009.invest"
Firefox actually has a small bug that is displaying the time as 2008 when it should be displayed as 2009. IE and Chrome both show it correctly. It probably has something to with the time difference. So that should not be what is wrong with the HamWeather system. The HamWeather system updated at 11:14 and I don't see anything that is wrong with the file.
The "invest_DELETE_al942009.ren" file has not updated recently so that couldn't have thrown it off. There is no renumbering file wrong, so it could not have been that either.
The file was updated off the normal schedule. The 0Z update was added and then later at 10:56PM EDT(tcweb directory)/10:58PM EDT(btk directory), they made another update. But that happens sometimes when they make an adjustment to the information for the previous history of the storm and perhaps for another reason sometimes the file just gets updated.
The only difference I see from the 18Z and 0Z positions, other than coordinates, is the radius of the last closed isobar. I didn't see what came out at 0Z tonight so I don't know if they changed that then or later.
At 18Z:
The last closed isobar has a pressure of 1010 mb. The radius of the last closed isobar is 180 nautical miles.
At 0Z:
The last closed isobar has a pressure of 1009 mb. The radius of the last closed isobar is 125 nautical miles.
So it is less broad now.
But still can't figure out why the invest doesn't appear. Oh well, a technical glitch on HamWeather's end I guess. Their main site has the same error. Unless the ATCF database does have an error I am not noticing. I know that database does get errors. I have to go coding up solutions for its quirks sometimes. (sometimes temporary solutions, like when they didn't release a renumbering file for one of the last storms that was active in the Atlantic) |
