Hurricane Paula • Moving NW at 10 mph; 992 mb ; winds: 75 mph • Paula rapidly intensified from tropical disturbance to hurricane in ~ 12-18 hours. • Environment to continually get less conducive for development as shear increases and dry air inhibits strengthening • Paula is a small hurricane with most convection offshore of Central America. • Final track will depend on the strength of Paula as steering currents break down by Wednesday • Paula could wander east of the Northern Yucatan all week
Rainfall Suppression across Central America IR Temperatures (K) / 200-hPa Velocity Potential Anomalies Positive Values (Brown contours) – Conditions not favorable for precipitation Negative Values (Green contours) – Conditions favorable for precipitation Central America under the Suppression phase of the Madden/Julian Oscillation (MJO) which will help inhibit precipitation
Ensemble Mean GFS MJO Forecast – OLR anomalies Ensemble GFS MJO Forecast MJO forecast to weaken in amplitude and continue propagating east during the next week Suppressed convection over Central America forecast for the next week
