Latest satellite images indicate that the low is now located east-southeast of Tampico moving to the north-northwest less than 10 mph. An elongated trough, the remnants of the northern low, extends to southeast of Brownsville.
Air Force recon is on the way and will give a much better idea of the structure of the circulation this afternoon.
The low is expected to become better defined over the next 24 hours and will likely become Tropical Storm Francine by Monday night. A track to east of Brownsville can be expected Tuesday evening with a gradual turn to the northeast likely Tuesday night into Wednesday.
The landfall target zone remains from High Island to southwest of New Iberia with the overall trend east of the Sabine. Landfall is expected Wednesday evening into early Thursday and there is a chance it will become a CAT1 hurricane.
If the track stays east of the Sabine, rainfall amounts in Southeast Texas, will not be very heavy as the heavy rainfall should be heavily weighted to the east side. Gusty winds in excess of 40 mph out of the northwest can be expected.
Obviously, further east, more significant impacts can be expected in Cameron and Vermilion Parishes.
