Area of Interest - Invest 97L

What was left of the old centerpoint was north of eastern Dominican Republic at 21/02Z near 19N 69W. Based on satellite data and radar imagery out of San Juan, the active tropical wave seems to be attempting to develop a weak relocated low center more to the East Southeast north of central Puerto Rico at 21/03Z. Still a bit early to tell for certain but the area does have potential for additional slow development. The windshear zone to the north and northwest of the system is still evident in satellite images, but the trend has been for a slow decline in the size and strength of the shear zone based on upper air analysis. The primary key to future motion will be associated with the westward extension of the Atlantic ridge. If it holds, system should move more to the west - if it pulls back to the east, motion will become more northwesterly. The good news is that steering currents are not very strong, so until the shear zone breaks down a little, forward motion is going to be slow.
