5PM EDT 29 July 2011 Update

Some of the rainfall associated with Tropical Storm Don is reaching Brownsville now, but actual center landfall north between Brownsville and Corpus Christi will occur late tonight.

The wave in the Central Atlantic hasn't changed much during the day, and still has a 30% chance for development over the next two days. The northern Leeward islands will want to continue to watch this system. What do you think the wave in the Atlantic will do? Let us know in the forecast lounge

Original Update
Tropical Storm Don's last day over water is today, and it is expected to make landfall very late tonight into tomorrow morning, probably in Kenedy county, TX, or just north of Brownsville. If the system sees any more movement to the west than expected, points in extreme Northeast Mexico could also go under a Tropical Storm Warning.

The system still is being sheared, and still has to deal with dry air, which will likely keep it from strengthening too much. Some strengthening is expected before landfall, but the limiting factors will keep it from going too high. Although there is a chance that convective bursts may occur as it approaches land so rain could be very heavy in spots.

The rain is being sheared mostly to the south of the system, points north of the center of landfall will not receive as much rain as points south.

Don will be monitored throughout the day, Those in the warning area should know that the hurricane center fully updates Every 6 hours, which includes (Times CST# 5AM, 10AM, 5PM, 10PM, and also issues intermediate advisories when there are watches/warnings up at 7AM, 1PM, 7PM, and 1AM. If a very rapid change were to occur they will issue a special statement #Usually after recon findings#, these are rare, but could happen anytime. So you can schedule checks around those times.

The wave in the Central Atlantic is now being tracked as 91L, it is expected to move into or close to the Caribbean, and has a 30% chance for development. If this were to become a named system before August 1st, it would put us at 5 named storms by the first of August, which has only been topped by the 2005 season recently. For comparison, 2004 the first named storm #Alex# did not form until August 1st.

Those in the Eastern Caribbean islands will want to watch the wave closely as it likely will develop before nearing the islands. This system has very few negative factors and will likely become this year's first hurricane. If so it would be named Emily. There is more speculation on this system in the forecast lounge.
