000 WTPZ43 KNHC 082035 TCDEP3 Tropical Storm Cristina Discussion Number 3 NWS National Hurricane Center Miami FL EP032026 300 PM CST Mon Jun 08 2026 Cristina is a sheared tropical storm this afternoon. Deep convection had been partially obscuring the low-level center until a couple of hours ago. Now the coldest cloud tops are concentrated to the south of the exposed circulation. Subjective and objective satellite estimates range between 32 to 40 kt. The initial intensity is held at 40 kt in deference to the earlier scatterometer data. The tropical storm continues to move northward at 5 kt, nearing the coast of Nicaragua. A subtropical ridge is located north of Cristina and should turn the storm northwestward on Tuesday, parallel the coast until landfall. However, this scenario seems tied to the depth of the cyclone, and is at odds with the monsoonal low-level flow bringing the center closer to the coast. The official forecast remains on the eastern side of the guidance, closest to the latest ECMWF and just west of GDMI. This track forecast brings the center over land sooner than the previous prediction, however any adjustments further northward could significantly change the timing of landfall. Competing factors make the intensity forecast somewhat uncertain. Strong deep vertical wind shear is expected to plague Cristina for the next couple of days. However, high sea surface temperatures (29-30 degrees C) and a moist mid-level environment do support further strengthening. The official forecast shows some gradual intensification for the next couple of days until the effects of land are expected to cause weakening and dissipation by the end of the week. Key Messages: 1. Heavy rainfall associated with Tropical Storm Cristina will impact coastal portions of Central America through Thursday. This rainfall may produce life-threatening flooding and mudslides, especially in areas of steep terrain. 2. Tropical storm conditions are expected to reach the coast of Nicaragua, El Salvador, and Honduras as early as this evening.
