At 21Z yesterday, Kyle was downgraded to a TD, experiencing fairly strong vertical shear and undergoing what appears to have been circulation splitting. However, as of 15Z today, he was re-upgraded to a TS based on satellite estimates. The location at 15Z was 28.0N 67.3W and motion was stationary. Winds are 35kts and MSLP is 1005mb. The forecast is for persistence... same place and same intensity for the next three days. A Tropical Storm Watch is still in effect for Bermuda. The real concern is Hurricane Lili, who continues to intensify on her track over Cuba and toward the U.S. Gulf coast. She has passed directly over the Isle of Youth and is over extreme western Cuba now. Aircraft flying into the storm have reported that the eyewall has been damaged by the passage over land, and IR satellite imagery confirms that the central convection is slightly weaker. However, this is almost certainly a temporary disruption in the intensification process... and an expected one. Lili will soon be over the open Gulf waters, which are warm enough to support a major hurricane. Shear is very low through the storm and is expected to remain low. At 15Z today, Lili was at 21.8N 83.7W and tracking WNW at 11kts (note the increase in speed compared to during the weekend). Maximum sustained winds are 80kts (nearly CAT2) and the minimum central pressure is down to 971mb. A Tropical Storm Watch is in effect for the northern Yucatan Peninsula, and a Hurricane Warning is in effect for the Isle of Youth and western Cuba. I strongly suspect that a Hurricane Watch will be issued for LA and eastern TX by later today. Early this morning, I spoke with Hucky Purpera, the Natural and Technological Hazards Division Chief at the Louisiana Office of Emergency Preparedness, and although nothing has been ordered yet, he believes their meeting this afternoon will initiate evacuations. Precautionary evacuations need to begin very soon, since landfall is only about 48 hours away (volunteer evacuations are always appreciated for those who wish to do so). Recommended evacuations should begin tonight or early Wednesday morning, and mandatory evacuations should begin midday Wednesday at the latest. The official forecast is for landfall as a moderate CAT3 hurricane on Pecan Island, LA on late Thursday morning. This is about halfway between New Orleans and Galveston, so a track deviation could put either of these major cities at risk. A storm such as this will force everyone south of I-10 and in her path to leave; this could include Cameron, Lake Charles, Baton Rouge, and/or New Orleans. See http://www.dotd.state.la.us/maps/lacoastlandsurf.pdf for a very good coastal map of LA and evacuation routes. LA has only experienced 12 major hurricane landfalls in the past 103 years, so it's not an every-year occurence! Elsewhere, a tropical wave and associated 1011mb Low is located at 10N 55W and moving W at 10kts. There is a well-defined surface circulation, but convection is sparse and the system is disorganized.Please visit my tropical Atlantic headquarters.

Kyle still a TS and meandering, Lili nearly a CAT2 hurricane over Cuba.
