The Satellite Presentation Of Cristobal Has Become Much More Symmetric Than At Any Earlier Time During Its Life.

The Center Is Embedded Within An Area Of Deep Convection And A Warm Spot Has Become Evident In Recent Visible Satellite Images. T-Numbers From Both Sab And Tafb Are 4.0 On The Dvorak Scale And The Initial Intensity Is Set At 65 Kt. Some Strengthening Is Expected Today While The Hurricane Remains Over Warm Water.

The Cyclone Will Begin To Interact With A Frontal Zone Tonight And Should Complete Extratropical Transition On Friday. The Global Models Indicate That The Extratropical Low Will Remain A Powerful Cyclone Over The North Atlantic During The Next Few Days. The Low Is Forecast To Merge With Another Large Extratropical Cyclone Over The North Atlantic In 3 To 4 Days.

Cristobal Is Moving Northeastward At About 23 Kt. The Cyclone Should Continue To Accelerate Northeastward In The Mid-Latitude Westerlies During The Next Day Or So. The Updated Nhc Track Is Close To The Previous Advisory And Near The Middle Of The Guidance Envelope. The Track, Intensity And Wind Radii Forecasts Of The Extratropical Low Have Been Coordinated With The Ocean Prediction Center.
