NOAA reconnaissance continues into Tropical Storm Isaias today after their most recent P-3 Hurricane Hunter aircraft returns home from its 7-hour mission tasked by the Environmental Modeling Center (EMC), which took off at 4:30 AM EDT Saturday, August 1st.
Tropical Storm Isaias’ convection illustrates the storm’s battle with vertical wind shear and dry air apparent via radar and satellite imagery today. The National Hurricane Center (NHC) expects this meteorological configuration to persist over the next day as the storm tracks to the northwest through the Bahamas before recurving toward the north. Isaias will track over the warm Gulf Stream waters as it turns to the north, which NHC predicts will allow for brief re-intensification.
La información combinada del radar Doppler de cola a bordo, la sonda de caída, la SFMR y los sensores de nivel de vuelo sugiere que la cizalla del viento vertical de nivel medio ha obligado al vórtice de Isaías a inclinarse con la altura, limitando la posible intensificación del huracán y exponiendo su núcleo al aire seco en los cuadrantes oeste y sur del ciclón.
NOAA reconnaissance data have been ingested into operational weather models since missions began on July 31st. NOAA’s P-3 took off today at 5 PM for its second mission of the day, and subsequent missions are planned through the weekend to monitor the evolution of Isaias.
