UPDATE 2010-11-09: B scans (level 3 data) are now back up. Issues remain to be resolved, but they are being addressed, and should be transparent to EWR users.

I’ve taken my level 3 data displays offline temporarily, due to data issues from the NWS. Apparently a server change was made for the level 3 data on the public server system without adequate consultation with the service managers, resulting in user inability to access and obtain the data stream. Attempts to mitigate the problem client-side have only been partially effective, as the problem resides in the source servers. We have been advised that resolution of this problem will not occur before Monday. Our scan A level 2 feeds continue to flow as usual, and, while no severe weather is expected in our target zones, the alert system is not dependent on level 3 data and remains operational.


Joe Bastardi of Accuweather thinks that, combining the La Nina, cold PDO and Arctic volcanic activity, the three winters starting with 2012/2013 could be as severe as the late 1970s (originally published Sept 8, 2010):

Wracked by a strong earthquake previously and only recovering at a brutally slow snail’s pace, the recent cholera outbreak may be the least of its problems in the coming days. A late season hurricane, Hurricane Tomas, is churning into the Gulf of Mexico after beating up the Lesser Antilles earlier last week. Strong wind shear is presently keeping the low pressure centre of Tomas decoupled from its rain core, lowering its strength currently to tropical storm status, but the shear is expected to moderate by mid-week, allowing the storm to turn toward the north and strengthen.

At least one model forecast puts the potential for Tomas to come across Haiti from the south as a major category 3 hurricane, which, if it unfolds, will cause severe devastation across the already ravaged country.

Update 2010-11-05: Hurricane Tomas has regained category one hurricane strength as it moves over the warm waters at the western edge of Haiti. Furtthern strengthening may occur over the next 24 hours before a decline in strength occurs. While winds are strong, the major threat from Haiti is very heavy rains. The cyclone has gained some orgaization this morning, and moiture content is high as evidenced from the 5AM GOES look this morning (below). Light blue traces over the centre are reconnaisance aircraft flight paths. Further discussion of Tomas is found lower down the page.

Coloured, numbered dots are track models and SS category strength levels. The yellow rings are tropical storm wind extent, red rings are hurricane wind strength. White dots are the expected path. Light blue tracks over the low pressure centre are reconaissance aircraft flight paths.
