This morning, it’s tied for fifth place with hurricane #4 in 1926, and is lagging behind hurricane Kyle (2002) at 22 days, hurricane Inga (1969) at 24.75 days, hurricane Ginger (1971) at 27.25 days, and finally, hurricane #3 (1899) at 28 days. However, using the latest official National Hurricane Center forecast, Nadine is expected to remain a tropical entity for another 1.25 days, and if that verifies, Nadine would jump into fourth place.
At the 11 a.m. advisory, Nadine is a weakening tropical storm with 50 mph maximum sustained winds, and is located about 405 miles west-southwest of the Azores islands. It’s falling apart quickly now, and would need a miracle if it’s going to come back for another encore.
A recent satellite image (above) shows an exposed low-level circulation (I marked the center with a red L) and the colder (whiter) cloud tops associated with strong thunderstorms are all located to the east and south of the storm’s center.
New tropical depression: TD15
Models are in excellent agreement that this disturbance will become tropical storm Oscar very soon. The track forecasts take it north a little further, then recurve it to the northeast, passing near or over the Azores this weekend.
On Monday morning, the decision was made within NOAA to begin moving GOES-14 eastward to replace the GOES-13 satellite that suffered significant instrument anomalies on September 23. While engineers are still working to repair GOES-13, it’s possible that it might not be fixable.
GOES-15 is situated over 135W to provide coverage for the eastern Pacific and western U.S., GOES-13 is situated over 75W to provide coverage of the western Atlantic and eastern US, and GOES-14 has been in orbit as a spare and is situated at 105W (between the others in case one of them should fail). Beginning this past Monday, GOES-14 is being manuevered eastward at a rate of 0.9 degrees/day, which would bring it to 75W by November 3, if GOES-13 isn’t repaired by then.
