"Nadine" Still in E.Atlantic... "Mirium" Weakening South of Baja in E. Pacific....
Take note of the ragged cut-off & bad data over the far E. Atlantic. The problem is that the GOES-13 satellite is malfunctioning. Work is ongoing but for the time being the satellite that usually covers the Western U.S. & parts of the Pacific has been moved east to cover more of the Atlantic Basin. Click here for info. from the Cooperative Institute for Meteorological Studies (CIMSS) & to view other satellite sectors.
"Nadine" is in the far E. Atlantic & slowly moving south/southwest toward warmer sea surface temps. A fairly well defined but wide center is evident on satellite imagery. Some strengthening should occur the next few days as "Nadine" makes yet another loop but stays far out in the Atlantic well east & northeast of Bermuda. The storm could revisit or at least come fairly close to the Azores again sometime next week though the steering pattern is rather muddled & complicated near "Nadine".
The Atlantic is otherwise quiet but an area to watch will be the Gulf of Mexico, Caribbean &/or SW Atlantic as an old frontal boundary/surface trough will set up shot in this region for an extended period occasionally reinforced by passing upper level troughs of low pressure. Surface pressures will be quite high across the Northern U.S. & NW Atlantic, so the atmosphere should respond by developing low pressure to the south. There are clusters of t'storms in the SE Gulf & parts of the Caribbean at times but shear is quite strong. Nothing concrete to hang one's hat on at the moment but something to watch in this type of pattern + such an occurrence is not unusual later in the season. Forecast models are showing a cut off low developing near the Gulf Coast next week which could lead to gradual surface development in the Gulf, so we'll watch how that evolves in the coming days.
"Miriam" is rapidly weakening in the E. Pacific well west/southwest of the Baja Peninsula. Some tropical moisture could advect northward into parts of S. California, Arizona & New Mexico by next week.
