Subtropical Storm Alex Arrives in the North Atlantic
OUT OF SEASON SUBTROPICAL STORM FORMS OVER THE FAR EASTERN
SUMMARY OF 500 PM AST…2100 UTC…INFORMATION
ABOUT 785 MI…1260 KM SSW OF THE AZORES
MAXIMUM SUSTAINED WINDS…50 MPH…85 KM/H
PRESENT MOVEMENT…NE OR 55 DEGREES AT 14 MPH…22 KM/H
MINIMUM CENTRAL PRESSURE…990 MB…29.24 INCHES
The NHC's forecast discussion concerning Alex adds that:
The cyclone is co-located with an upper-level low, and appears to have only a weak warm core, so it is being designated as a subtropical storm.
By 96 hours, the global models show the cyclone merging or becoming absorbed by another extratropical low at high latitudes.
Alex is the first tropical or subtropical storm to form in January since an unnamed system did so in 1978, and is only the fourth known to form in this month in the historical record that begins in 1851.
The NHC suggests that, unlike Pali, Alex may pass near some human habitations:
WATCHES AND WARNINGS
Interests in the Azores should monitor the progress of Alex.
