Ike Coming Ashore and Watching to the Southeast

The area of disturbed weather to our southeast is being watched for development which is not imminent at this time but we will continue to watch it. Below are the latest model runs which bring it very close to Florida in many cases. Intensity models are split between a tropical storm force system forming or a system that remains relatively weak. Below are the tracks.

I am currently watching live coverage of Ike coming ashore Texas at this time with winds of 110mph. If you have DirecTV you can tune to channel 361 and see the live, local coverage from KHOU-TV. They recently reported 300,000 customers are already without power. Make that 315,000 now.

Also of interest is that their hurricane specialist is Dr. Neil Frank, former Director of the National Hurricane Center.

Check back tomorrow for an update on the system to our southeast. Updates will also be on Twitter.

Live Coverage of Ike

You can listen to KHOU on channel 247 on XM Radio and also live audio and video and DirecTV channel 361.

Disturbed Area of Weather East of Florida

According the the NHC this area has a 20% (low) chance of developing into a depression as it moves towards the west. Earlier this evening the convection had died down but has come back a bit in the past couple of hours.

Earlier today there were some models run on this system and their output had the system going anywhere towards the north to the west, including south Florida. I will have further updates tomorrow. Please note that there were no model runs on this system tonight but may resume tomorrow if the convection continues. Check back tomorrow for an update.

A New Area to Watch

A new area of weather has developed in the Atlantic that the models have picked up on. Some of the models bring this system as a tropical storm into our area.

11PM Adisory on Ike

Just read the 11PM package for Ike and the five day forecast point is 26.0/80.0 or just offshore Broward county with 130mph winds with gusts up to 155mph. This is a five day forecast with a large degree of error in both location and intensity

Ike and South Florida


With the 5PM NHC forecast point less than 100 miles off the coast of southeast Florida all attention is turning to Ike. Just looked at the 8PM early cycle models and as they did six hours ago many of them point right into the area. Intensity models of these models range from borderline cat 1/2 up to cat 4 (HWFI and AVN).

The official local forecast has "hurricane conditions possible" for Monday night and Tuesday day. Please take time on Friday not only to keep track of Ike but to go over your emergency supplies and plans and make sure you are ready for Ike. This appears to be our biggest tropical threat since Wilma.

More frequent updates here and through Twitter, stay tuned.

Watching Ike

From this morning's Hazardous Weather Outlook:

HURRICANE IKE LOCATED OVER THE ATLANTIC NORTHEAST OF THE LESSER
ANTILLES IS FORECAST TO MOVE WESTWARD THROUGH THE WEEKEND AND MAY

DANGEROUS CATEGORY FOUR HURRICANE. RESIDENTS AND VISITORS IN
MAINLAND SOUTH FLORIDA SHOULD CLOSELY MONITOR THE PROGRESS ON
HURRICANE IKE AND BE READY TO ACT SHOULD THE HURRICANE THREATENS
SOUTH FLORIDA.
